DAC 394 (Sig 228 Clone) Kit

got my light firing pin strikes sorted, needed some filing on the firing pin safety block to clear the pin. Off to the range tomorrow, then Id like to organize a DAC 394 mission range shoot for anyone in the area. Joe boy, effects, mp5k..... The winner gets a stock dlask mag with a cracked base!
 
I'm headed to the range tonight to try out the new hammer swing a la MiltonBradly modification to the mainspring saddle and the firing pin rounding a la joe-boy, and the new slide pins a la moi. Now if I can just hit the paper a la a wing and a prayer.
 
:) Woot!!!

My project isn't finished yet.

So I shot two rounds this evening. :(

Great pin strikes and no FTE!:)

The main spring saddle slip forward off the hammer pin both times. I must have put too large a radius on the saddle when doing the MiltonBradly mod.

Even without firing, with the hammer cocked back, if I push forward (by hand) on the mainspring leg with a tap, it slips off the hammer pin. Could it be that the hammer cross pin is forcing the hammer saddle so far down that the saddle and hammer pin separate? I will have to investigate further.

You still have lots of meat there to play with... Maybe pull the hammer and inspect how it interfaces with the strut as it transfers from cross pin to pivot pin. If it is sliding forward so that the saddles cross pin notch ends up sitting on the pivot pin you might just need to grind the "peak" between the notches back a touch to guide the pivot pin into the correct notch. I polished my notches and edges a little bit as well to try and reduce friction, perhaps something is snagging up against a rough edge and throwing things off track. I know my trigger bar "ear" (the bit that pulls the hammer back in DA) was dragging against the strut during the trigger return stroke sometimes and causing the trigger to not fully reset for a DA pull... Look for the unexpected gremlins as well as the obvious...

Have you lightened your hammer spring? I have a feeling that the stock spring is a good %100 stronger than it needs to be once all the other "factors" are resolved. Less preload might cause less tenancy to "jump the rails" as it were...?

Right on the money! When the strut was lifted off the centre hammer pin and then on the hammer swing forward, the peak between was sometimes guiding the strut back on to the main hammer pin with the cross pin area of the strut resting on the main hammer pin. After "moving" the peak backwards with a file, the strut can't get there any more.

I have cut two turns off my main spring. Should I cut more?

Thanks for your excellent insight!

Well... hard to say... It the primers are getting a really good whack then sure, if there just getting a light dent then no. What is "enough"? I have no clue...

I am running off the theory that if I cut a spring too far but can still shim it back up then all is well. Do you reload? If so you can test your strikes on empty cases with fresh primers (that's what I'm doing). I have dropped in a 19lb 1911 spring that is both lighter and shorter than the stock spring. I'm still setting off primers but the DA ones look really light. I'll likely shim the spring a bit with a small cylinder of steel to up the preload until I feel I have enough extra energy to set off even a poorly seated or hard primer. Note that DA has a shorter hammer stroke than SA (at least mine does) so ensuring that DA strikes hard enough is critical.

P.S. You do realize I'm making this up as I go along right?... :D
 
Went to the range, 100% relibility, 300 rds with no FTFs, no FTE, no stovepipes, nothing.Accuracy was good, but not great. Pistol feels great to fire, a bit on the heavy side but low recoil is the benefit. Ive got a great single action trigger but quite a heavy dbl action, compared to my 226. Bottom line, an advanced pistol smith course for $200, with a free 9mm thrown in!

Great to hear! 100% on 300 rounds. That's great!

When are we going to go to Mission? :)
 
Alrighty, Finally got mine together except for the grip screws, Thank you effects for the pins and Joe for the Screws.

Now i just need to find a bit to enlarge the existing grip screw holes on the frame.

It was a challenging project but in the end it turned out to be a great learning experience for me. Took me around 30 hours spread over 2 months.

Sushi, you are now a member of the ultra-cool DAC Armourer's Club. Women will now start calling you out of the blue, buying you beer and offering themselves as prize trophies for your awesomeness.

looks like mine! Did you get all the bugs out yet? About 35 hrs spread out over 3 wks, A lot cosmetic or tuning. Going out again today to test some light dbl action strikes & a loose mag catch plate, both i hope are resolved now!

Is your BC near Mission Range??
 
I haven't shot it yet, but yeah my trigger bar does bind against the mag sometimes. Also, my hammer spring feels a little heavy because my DA is like 20 pounds or even more, it makes it very hard to #### the hammer with the slide.

Very nice to see people getting into projects like this and actually learning something. Some of the issues kind of scare me, but hopefully most people have the sense not to even attempt to fire it until it is functioning 100%.

After reading five pages of posts I definitely want one of these kits. Are they all sold out now? If anyone reading this post has one and has become discouraged by the work involved, first I suggest that you try to finish it anyway, second PM me and I will take it off your hands. :)
 
light dbl action strikes fixed, mag catch plate still popping off, guess ill have to make one. Brass hitting me in the face sometimes, ouch! Angled the ejector slightly. 100 more rounds, no probs with feeding or ejecting. Accuracy OK, But not as good as my real sig or glock, but for $199....
 
Went off to the range tonight to test out the build. 200 Rounds and no failures at all. Shells eject nice and solid. Single and double action works. Did have to break in the magazines by leaving them loaded for a day or two. Accuracy for me was pretty good even though the sights are just utter crap. Thinking of getting some night sights. In the mean time, I went ghetto and used some white out to fill in the front sight hole.
