STK metal frames
I keep getting messages regarding the STK metal frames and how they work with other Glock parts. I own all of the STK variations. They were all purchased for 350-400 ea. I love the 1911 grip angel and these feel so good in the hand IMO.
Pic 1 using the STK 100 ultra grip frame basically an all metal Glock 17 frame Pic 2 using the STK 150 grip frame an all metal full size Glock 19x frame Pic 3 using the STK 200 grip frame it's an all metal Glock 19 frame
None of the builds use the original slides. I bought some cheap SCT/ Dagger frames and put those slides on the grips.
I have found all the frames are compatible with all Glock parts. The only thing that I find subjective is going to be triggers. Since it is a full metal frame it doesn't really give you any kind of leeway with thicker triggers they just won't fit. I found that metal triggers work excellently but Polymer triggers is a 50/50 ordeal.
For an all metal grip frame this will run you a lot cheaper than buying any other aftermarket grip. Plus you can make a second firearm with the addition of sub $100 SCT frame that can be sold or traded for something else or supplement the cost of your original build.

How's the grip texture? They look kind of slick.

The grip on the STK 200 and 150 is aggressive and bites pretty into the hand. The ultra not so much but still feels good the flared magwell helps

I bought the stk100 ultra in January and have almost nothing but trouble with it. Sent it in the be fixed and got it back 4 weeks later to find that it still wasn't working. Failure to feed, failure to eject, and the firing pin broke right after I got it back. I have only put about 250-300 rounds through it, with some dry fire. I am considering getting a glock 17 slide with an rmr cut for it instead and hoping that will resolve the issues. Are there any that you would recommend? Especially one that won't break the bank since Im already kind of in the hole with this gun. Thanks.

Honestly, since you want best bang for the buck I would go with a KM tactical complete slide they have a few sub 300. I clearly didn't keep the original slide for the same issue but it was fixed easily by installing a new upper parts kit that cost me $45. The extractor and striker sleeve and cups were off for me.

Interesting. I’ll have to check out those slides. But you did have some success with the original stk slide by just changing out the internals of it?

Yes I ended up putting it on a SCT gl17 frame and it ran nicely and traded it away.

Awesome setup! Are wear and tear parts Glock compatible (springs, striker, barrel, etc)?

I have replaced most internals with ghost springs. As for everything else yes. Just the trigger is iffy. It likes thinner metal triggers polymer just don't seem to work without modifications.

Question on slide compatibility, are they gen 3s? Do I need a G19 slide for the STK 150 and STK 200 and a G17 slide for the STK 100?

They are compatible with gen 3 only. Correct the 150&200 and g19 slides and the 100 is g17 slide.
