I would like some feedback on this .22, If you own one do you like it , how doesd it shoot how do you find the grip to big, too smal:canada Flag:l .I have a 12 year old boy who would like to shoot pistol. He already has a .32 cal bp.rifle and a .22 of course so I would like to round out his collection.
 
Don't personally have one but always keeping my eyes open for a good deal on EE. You're going to find that here on CGN you'll get a real mixed bag of reviews of the Mosquito. Some people hate them and some people love them. The haters mostly complain about them being very picky with ammo and if you can't find the right ammo then they're "jam-o-matics". For the people who have found ammo that works for them
they love them and enjoy shooting cheap ammo while honing in on their skills. If you do a search you'll find a few threads on the mosquito but like I said it seems like it's almost 50/50.
 
I had two (only have 1 now) but it is a great pistol. Like everything else there can be bugs with it but it is almost always ammo related. In a nutshell, if you are looking for a .22LR pistol that "feels" and operates like a full size pistol, then get a Sig - it is like 90 percent smaller then a normal Sig. If you are looking for a pistol that will shoot everything reliably and never jam, then don't buy a 22LR pistol because I have yet to see a semi auto .22LR pistol/rifle that is 100 percent reliability - mainly because 22LR ammunition varies so much in terms of priming, bullet shape, powder charge, etc. If you want something is pretty reliable with lower costing ammunition - the Ruger Mark 2/3 semi pistols are pretty good and inexpensive. Just my 2 cents. I find that many of the people who hate the mosquito's, frequently dislike the fact that they can't buy the cheapest ammunition and have the pistol operate 100 percent reliably. I experience jams with Dynapoints/T22/etc but with Stingers/Velocitors it is very reliable.
 
My wife loves her Sig Mosquito. Has been shooting it for 4 years, still in the case to shooting range every time.

We buy CCI Mini Mags for it only, because it cycles 100% in this gun, not one jams so far. We have not tried other ammos.

The Mosquito is slightly smaller than Sig P226. It fits well in both adults' and kids' hands.

The only problem I have with this gun is the trigger - it is very bad. Rigid, long, with a tough breaking point. This usually results in larger groupings. But the flip side is that if you master this trigger, all other guns seem to be very easy to shoot and easy to shoot well.

I'd recommend the CZ Kadet myself. Nearly 100% reliable and it shoots whatever goes into it. Being that it's for his son, the reduced size of the pistol would likely be a good fit. I found it to be too small and prefer the full size of the Kadet.
 
I would buy Sig Classic, IMO. It's a few hundred more and you'll end up with full size Sig P### and later you can buy conversion for real ammo. :)

I bought P220 Classic, I fired over 800rds with crappy Thunderbolt ammo. It jams 5% of the time when chambering first round and bends the lead tips. It's better if I slowly close slide to chamber 1st round. Very few FTF and once that first round is in, it cycles just fine. I like unloading all 10 rds in under 3 seconds. Hehe...

I bought the aluminum follower upgrade to make slide lock back after last round fired. It work well with first 250rds and it doesn't work anymore. LOL! I dried fired it 30+ times by accident (yeah, got carried away). I don't notice any scuff mark in the barrel nor any pin flattening either.

I don't have any conclusive evidence about dry firing Classics unintentionally. Sig's website and manuals says don't but someone got response from Sig's CS and said it's okay b/c there is some feature that prevents firing pin damage when no round is chambered. Beats me, but it so far looks fine with my Classic.
 
I have one and it performs very well for a .22 pistol. As long as you use standard velocity ammo (<1150 fps), as the instruction manual suggests, you won't have feed issues. I've tried high velocity, winchester wildcats - they were all we had, and i had the occasional jam. The case expands and jams up in the chamber. Keep it clean, keep it lubed, follow the instructions and it'll run trouble free.
 
I sold one and regret it. It was fun and reliable, but it is a bit of a crap shoot, there are a lot of lemons out there too from what I read.
 
Mine wouldn't even work with CCI Minimags, didn't matter what spring was used either. I got rid of it.
 
i like mine, it seems to like stingers the most. it really liked stingers with the light spring in it, although i'm not sure if that will wreck anything. i find it to be more reliable than my ruger mk3, which is hit or miss with cycling(unless i use stingers). my nine year old son loves shooting the mosquito, it is easy to operate, but as another poster said, it has a terrible trigger. at the risk of getting in trouble for saying this, it is one of the coolest toys you could let your son play with.
 
I own one, and bought one for a friend. Reliable for us and we use remington yellow jackets, $37 for 500 .22LR so not bad. Fun to blast through, but for a younger person might be frustrating to learn with since trigger is long and break point is rough. This will lead to large groupings and might discourage a new shooter to the sport.

A Ruger Mark (even though I hate how they look) are WAY more accurate and could be more rewarding for someone new, if that would even matter to him.

Sig Mosquito for first gun? No way.
 
keep it clean

Recently my mosquito had gotten very dirty, to the point it would not fire 2 shots in a row. I sprayed the heck out of it with shotgun cleaner and then used compressed air and then relubed it with cheap Canadian Tire spray lubricant and now it is back to 100% again . I use winchester 333's.
 
Mine wouldn't even work with CCI Minimags, didn't matter what spring was used either. I got rid of it.

Likewise. Fed mine Mini Mags and tried other brands of HV .22lr ammo. Couldn't get through a single magazine without some sort of malfunction. I didn't want to waste any more time on/with it because I have 2 other .22lr pistols (Beretta 87T and Ruger MkII GC) and a S&W 617 revolver that worked flawlessly right out of the box so I brought it back for a store credit. Others have reported that they are happy with their Mosquito and have had no issues with them. Can I recommend the Mosquito? No. YMMV......
 
i used to own one, i really didn't like the compensator much. made the gun look ugly.
also had a walther p22 and had the barrel shortened and compensator removed, nice little gun, great for small hands, which mine a little on the big/chunky side. sold them both. i kept my 22lr conversion for my sig p220, lots of FTF at the beginning, even with CCI ammo, it worked fine after a few hundred rounds. i guess it needed to be broken in.
