Seriously though I didn’t realize how many boxes there were and there’s more that couldn’t fit in the picture frame. Any ideas on what to do with more then one of the same kind.? Do these have a lot of value.?

Steel city arsenal Magwell + Magazine extension compatibility

Thumbnail
gallery
3 Upvotes

Recently added a steel city arsenal magwell to my pf940c and overall the ergonomics are incredible, changes the entire grip feel but in a more secure/stable way. I’m curious what magazine extensions work with it, I’ve been between purchasing the Glock Store extensions or the Sheild Arms extensions. My main concern is the top ridge / lips of the magazine extension blocking the magazine from being inserted fully due to hitting the magwell. If anyone has a similar set up and any advice I’d love to hear it.

Geisler Defense 19x Rear Rails

1 Upvotes

So I’m looking into grabbing a Geisler Defense frame, but most people say the front rails sit really high. Then I see other people’s builds, and everything looks nice and flush. Is it just hit or miss, or is there something people do to make them fit?

tip for building 76% frames with split rear rail modules!

Thumbnail

when removing material from the cavity that the trigger housing goes in, make sure to remove material until the RRM and trigger housing is easy to insert and remove from the cavity. if the cavity is too tight, it could cause the connector spring to be compressed, leading to trigger reset failures.

this doesnt happen with one-piece RRMs because its impossible to fit the RRM in until more than enough material has been removed, ensuring enough space is always available with builds utilizing them!

Brother botched a p80 build (actual 80 not 76) . He gave it to me for free and said if I can fix it I can have it .. he used a dremel and a crappy fine bit . Is this frame at all salvageable in any way or is it done for ?

As stated my brother totally screwed up this p 80 build and told me I can have it if I can fix it .. is there a way to Jb weld and redo this or is it trash? I told him to put the tools down because to me it looks like he totally screwed it .. any way it’s fixable ? I’d love to make it usable even if it doesn’t look pretty .. any help appreciated

Geisler takedown lever shim?

2 Upvotes

Guys I looked it up, but couldn't find any info. How do I shim my takedown lever on geisler gen 2?

Just found out today after bending and polishing my rear rails that when I dry fire my slide releases, meaning I'm having takedown lever issues...

I seen something in here about shimming the takedown lever, but couldn't find any info on how to do it properly.

Need Troubleshooting Assistance With Build

1 Upvotes

Hi, I have a recently built PF940v2 with all OE Glock internals, a Faxon barrel and a Brownell’s optic cut slide. The pistol operates fine and then the slide locks as though the mag is empty. The problem is the mag is not empty, furthermore the trigger seems to fail to reset during these failures. Once I release the slide lock a new round is chambered and the pistol will fire. Any ideas as to what is going on?
