Hello my fellow 1911 aficionados! New to the forum, not new to 1911s.
I recently bought new a Tac Ultra FS HC in 10mm. Only had the chance to shoot about 75rds out of it untill the magazine catch spring and locking pin made a jump for it at the range :(
As expected from the research I've done the factory mags (MecGar 40s&w I think) were not so compatible, so I found them difficult to seat especially loaded with 16rds of 200g 10mm. So I admit I'm a sinner, I would practice loading before the range and I was slamming on them a bit. Gun shot beautiful minus a few FTFs (again to be expected apparently as a magazine issue.) Then when I hand it to my buddy and give him a mag and tell him "slam it in there" it wouldn't lock in. He handed it back and I noticed the magazine release/catch assembly was free floating. I thought "well that's not right" and then noticed the locking pin and spring were MIA. Needless to say I hunted for them in the snow for longer I care to admit.. Anyway, I already ordered a new spring and locking pin for a whopping $7 and am optimistic of them working in my new Rock Island despite RIA being mostly mil spec, correct? I have another Philippino made Cimmeron 1911 A1 (also metric for some parts I assume) and have swapped a few parts with no issues.
My question is this. What caused this to happen? Was it me slamming the mag in just a few times like an amateur? I would expect magazine damage before anything, splitting the lips and whatnot. Also I'd like to know if this has happened to anyone else. I've looked around for a bit and heard of it happening on some Kimbers which was surprising.
Apologies for the novel and I also would appreciate any other input for other common issues with these, including the common FTF and the brass hitting the slide. Thank you :)

Probably more likely a combination of things-slamming the mag in hard (should have downloaded it if it was seating that hard FWIW) + pin being a little loose/undersized and/or the spring being a bit weak + the extra heavy recoil from the 10mm loads (10mm's tend to knock things loose and break things in general but that's the nature of the beast(s) anyway). If it happens again, get a heavier mag catch spring.

Thank you and you're probably right. I never checked the locking pin before shooting it. I was too exited :D It may not of been seated tight from the factory. I've caught a few minor factory errors on it already (metal shavings left on the thread protector, and other minor imperfections) and the spicy loads I was first shooting could of lossened something that wasn't secure to begin with.
I should receive my new spring and locking pin soon. Fingers crossed it will stay put once I put it in.
So I admit I'm a sinner, I would practice loading before the range and I was slamming on them a bit.
On this specific subject, you may find some useful information in this thread: Why is it so hard to seat the magazine and how do I fix it?

Fantastic post, definitely bookmark worthy. Thank you!

Update: just got my new spring and locking pin in the mail. Mag catch seems exquisite. Only need a thumb of pressure to lock the mag in just like on my A1 single stack.

Whether the issue was mechanical or intelligence lacking brute of an operator, it's fixed :D
