TTI HI CAPA - Slide not locking

is it locking back on empty when you manually cock the slide?

 
Have you short stroked it at all?

This is something that generally happens when you add too many buffers.

No modifications have been made to it, it was working fine until I took off the slide and changed the hop up which then started giving me issues 

 
Wedge the bb follower as high as it will go in the mag, then manually pull the slide back.

You said you took it apart, and you’re not fully conversant with GBB pistols, are you sure you have re-assembled it correctly?

You said it’s standard, but I don’t believe that magwell is?

With the slide off and an empty mag in, does the follower push up on the slide stop?  If so, that will rule out mag, spring, follower and slide stop issues and narrow it down to the slide stop/slide notch interface.

 
I think it’s something to do with the slide release bolt that I showed pictures of causing the issue, taking it in to the shop on Monday and will update what the issue really was.

thanks for your tips I appreciate the help

 
Are you inserting the slide catch pin back in with the slide pulled back far enough, so the "pointy bit" of the pin (that's missing a bit of paint) sits in the smaller of the 2 notches in your slide?

I fixed this for a guy at hells a few months ago, was the follower in the mag not pushing up far enough.

thats what I think. If it’s marginal, it might be the magwell stopping the mag inserting properly, and thereby stopping the bb follower raising enough 

 
The issue is to do with the slide release part.

A new part from a different hi capa would fix the issue however there was some movement when the magazine entered pushing the release part out a small bit causing you not to be able to press the slide release unless you push in inwards.

Is that what the shop said?

 
My TTI was a boneyard purchase which had a very sloppy slide lock / take down pin. I just fitted a spare one I had in my spares draw (possibly TM but wouldnt swear to it) and all good . Very easy fix.
