SRT Install Question

[9mmepiphany]

That is a famous lubrication thread; however, it would have been nice to have seen what happened after he put the SIG back together. Probably 50% of that grease ended up squished out of the back of the slide.

I've been in the shop when they put them back together and that doesn't happen...it isn't the way SIGs are set up as to the slide frame interface...it isn't like they are a tightly fitted 1911. (and Enos advises grease (Slide Glide) on the rails of 1911s too)

Many people don't know, but part of what helps the rails of well lubricated SIG alloy frames live longer is partly lubrication and partly hydraulics...the grease cushions the impact of the slide on the rails as it twist in recoil

I used clp on mine. Worked fine for me.

You are of course free to treat you gun however you'd like. I only offer advice for folks who want to prolong the life of their rails.

I've seen grease lubricated rails on a gun with 40k+ rounds look better than a gun with 10k rounds where the owner only used CLP or another oil on the rails

One thing i noticed with the grease is that the barrel never started to smoke like it did when I used clp to coat the barrel.

I just noticed an issue when I use snap caps in my gun after the SRT install. Basically the hammer doesn't fully reset. I think I need to reposition the hammer, but I wanted to get some feedback on what you guys might think the issue is.

you need to slightly round the bottom edge of the SRT lever. the bottom transition is too angular where its hanging up with the sear. what happens is that the sear bar is getting caught on the bottom of the SRT lever, and its not resetting. you need to round it by making it a bigger radius. file a little at a time and dry fire violently with the grip off until you get 100% reliability. finish both contact surface with polishing compound.

that is the secret. most people are too scar to pick up the file and take off a little at a time. so they charge you an arm and a leg for it.

if you are near LA/OC i can show you.

So the weird thing is that it doesn't have a problem dry firing, it's just when I have a snap cap in that it has that issue

I didn't have to file anything when installing the SRT on my MK25. Functioned flawlessly.

Tried real hard on mine... Nope... Everything works like a charm. Also, I don't see how snapcaps can cause it. Are you sure your SRT kit was indeed for 226?
Did your gun come with E2 grips, or did you install it by yourself? I have a feeling your hammer strut might be failing. Also it's worth checking the hammer reset spring (outside on the right when you remove the grips). It's very easy to clip or reposition it, when you install E2 grips.

If nothing works, install the original parts and see if the issue persists

It's just the opposite. You have to grease the rails.

Follow the link that 1nsanity provided. Scot really knows what he wrote about as they saw lots of SIGs come through the shop every year with terminal rail wear.

For training classes or long practice sessions it is common to float a layer of oil on top of the grease

9mmephihany knowwwwws! Grease and then more grease.. Can you run it dry? YES.. but it will cause premature wear on your rails..

Whenever I detail strip my Sigs, I grease everything.. The internals will feel like butter if you do.. CLP works, but it doesn't last as long when applied to the internals..

Looks like you didn't install the hammer back properly.. there's a hammer reset spring that needs to carefully positioned when you're putting everything back.. its tiny and easy to miss..

I would look at that before you grind/file anything off your gun..

And the snap caps have zero to do with it..

Looks like i bent the hammer reset spring.

you have to rack the gun and let the slide slam home to simulate / duplicate the real life condition where this happen.

cocking the hammer wont produce it.

it all really depends on the geometry and tolerance of all the parts. most guns are within tolerance thus that will be drop in. some like the 226 navy that i had and the one OP have is running into a tolerance envelope where hang-up could happen.

the internal are either MIM or metal stamping. the tolerance on it are at best at two decimals.

Neb-

It can be replaced, but you'll need a very, very fine punch and a new hammer reset spring..

Honestly, it's not something I would recommend unless you're confidant about your skills. It's nothing more than tapping the pin out and carefully tapping it back in.. but it does require a very delicate touch..

Let me know if you want to try this on your own and i can help you with some advice.. PM me..
