3 Gun Tips and Tricks

Shotgun mag springs

So I trimmed the mag spring in my pump gun to ease loading. Then I added a +2 extension that did not come with a new spring. I stretched the spring out, and it seems to cycle fine. The follower is still under spring tension, but it is very light when empty (in fact the spring starts to audibly rattle against the tube when empty...which is either a bad sign, or a cool new way to know it's time to reload). I tested by pointing the gun down completely vertically so the spring had to work against the force of gravity and it still works fine.

Any ideas for a test to make sure I have a strong enough spring to function reliably?

Stretching a spring is a short term, temporary fix. It will fail.
The only way to test function and reliability is to load to max and fire all rounds. If your last round does not feed properly it is time to replace your spring.
 
grim, the normal way to measure spring tension is to measure how much pre-compression is on the spring when the mag tube is empty. I ran my last semiauto shotgun at 7" and it worked well, but most people would advise at least 10" of precompression.
 
Did some work on my loading port. The SXP does not really lend itself well to this, but now I can quad load. EXCEPT....I have damn near torn my thumb nail off a couple times jamming it into the edge of the mag tube entrance.

Personally.... I never go below 12".

Very small benefit with a higher likelihood of ftf below that.... You gotta keep in mind shells vary in length as well, and you don't wanna have failures the one time you have to use different ammo
 
I am interested in possibly picking up some AT15 pistol mags but....

Do they fit into the Blade Tech double AR mag pouches?
I will be able to tell you tomorrow hopefully when mine arrive.

^ Nice job on hogging out the loading port!

Thanks! See the edge of the mag tube entrance nearest the barrel? I think that's what I keep trying to rip my thumb nail off on. Is this spot rounded on ready made 3 gun shotguns or is that normally part of a loading port mod? Or is it just my technique?

Most of the "3 gun shotguns" that I have seen still require some hogging out of the loading port. On mine (M3000) I had to hog out and smooth out the area you mentioned. Just be careful not to take too much out. I did not take out too much but rather, just rounded and smoothed out that area. Some others have taken more out though. There are some great youtube videos on this.

It's probably not the entrance. It's the end of the lifter and your thumb getting caught at the entrance. Extend the lifter.

I don't think I can. The lifter actually touches brass in the mag tube by half a hair width as it is.

These dummy rounds actually stick out a tiny bit more than any shells I've tried, but you get the idea:

I will smooth out the mag tube entrance and try again once my thumb heals, lol.

I've been out of the thread for a few weeks. I have my 3 guns I intend to use now. I do have a couple questions though.. Ive never attended a 3 gun comp yet but will start in the spring.
I would like to see some pics of what you guys are running for these comps and why.
Im going to use a glock 17, 870 and a Colt m4 16". The glock will remain stock for now. But I have a few options with the AR and the 870.
My questions are more in the details. Like with the ARs, what are you using on the forend? I have a few different parts. Also the 870s/shotguns, what stock set ups are proving most popular? standard furniture? Knoxx pistol grip style? magpul furniture?
My colt has a BAD lever, Raptor handle, and a crossfire II 1-4, and the grip. I have the handstop grip I could use instead? Im new to ARs, not shotguns and pistols. I have several options for optics, Red dots, irons, etc. Just trying to get a handle on where to be aiming.. I understand the "Run what you brung" but would like to get ahead of the curve since I have options available.
Thanks again for the info... keep it coming.

The setup that others are using has little to no bearing on performance. All the little add ons or adjustments are more for comfort than performance.

Pistol
-Run the sights you like and get to know them intimately.
-Your holser should be something solid and quality like kydex. Make sure your holster does not interfere with any other gear and that the holster doesn't slide around.
-A PURPOSE MADE gun belt is a MUST.
-Mag pouches should follow the same format as the holster, well made with good retention and not slide around or interfere with other gear.

Rifle
-A well balanced rifle is more important than a lightweight rifle.
-A free float hand guard is nice but not necessary.
-A quality reliable optic is an absolute must, same goes for the mount it rides in.
-The rifle must be absolutely reliable.
-Your magazines must be absolutely reliable.
-A QD sling is nice as not all matches or all stages require a sling
-A good compensator is likely the easiest and cheapest performance enhancement available... But it is not necessary
-Everything else(grips stocks, sights, triggers, etc) is just dressing and personal choice.

Shotgun
-It must be reliable.
-Spend your time on practicing loading the gun, this is where a match is won and lost from the shotgun perspective.
-Practice some slug work and know where your shotgun shoots.
-be very familiar with the operation of your shotgun.
-Aftermarket furniture is a personal choice(like the rifle bits above) however a rubber or rubberized fore end helps when hands are sweaty.
-Make sure your shotgun can mount a sling, QD helps.

Load bearing gear
-Personal choice as to whether you use a belt or a chest rig setup.
-Practice in your gear and make sure nothing interferes.
-Organize your mag pouches logically. For a right handed shooter placing your rifle mags on the centre to left side of the rig makes reloads easier.
-If the stage doesn't require pistol or rifle or shotgun, then don't carry that ammo or ammo supply system. Dump magazines you won't need for the stage.
-A folding or low profile dump pouch attached to your belt or rig can be a lifesaver if you need to carry more ammo. It also makes a great place to keep a water bottle and a place to collect your mags after a stage.


Shooter

-PRACTICE PRACTICE PRACTICE
-Think about each stage and find the choke points. It's best if you can watch others shoot first and see where they struggle.
-Don't load and make ready with the first mag(easiest reload) on your belt/chest rig.
-Always top up if permitted
-NEVER put empty or partial mags into mag pouches before a stage. Empty mags belong in a dump pouch or a pocket.
-Carry more ammo than you think you will need, you can't grab more after the buzzer.
-Drink plenty of fluids. I have a drink before the stage and always immediately after the stage. If there's a gap between stages or resetting I continue to drink fluids.
-Snack if permitted.

General tips
-HAVE A MED KIT OR TRAUMA KIT CLOSE BY. I suggest you bring your own and keep it handy, on your kit if possible.
-Baby wipes are handy as is a bottle of hand sanitizer
-Toilet paper, some ranges have less than stellar facilities and running out of TP is just as bad as running out of ammo.
-A change of clothes for after the match. Getting out of your sweaty dirty clothes is always nice and keeps the car clean. A lot of shooters will meet up after a match for a bite to eat or simply hang around and "tailgate" it.
-Sunscreen and bug spray
-Spare batteries for optics and spare parts if you have them.
-Pen and paper never hurts, you may want to network with other shooters.
-Bring LOTS of ammo and check your ammo for compatibility(steel core etc).
-If you have a spare gun(s) bring it.
-Bring all your magazines, replacing empty mags with full ones takes less time than reloading the empties.
-Bring the tools needed to mount/remove your optics or assemble/disassemble your guns. Bolts like to loosen up mysteriously.
-BE SAFE AND ASK QUESTIONS IF YOU ARE NOT CLEAR ON THE COURSE OF FIRE OR THE SAFETY RULES.
 
Good write up x.
Thanks for the info.
I am still curious as to what guys are running. I understand personal preference. Are the set ups a bit on the private/secret side? Like a car race where the guy won't pop the hood until after the race hahah

What works for one person may not for another. You need to try your gear and find what works best for you.
