Anyone ever get an armorer plate and look at theirs?

My 43x has significantly less engagement than my full size guns.

This is 100% factory parts.  Multiple trigger bars tried, same exact engagement.

My full size guns don't have this much downward play when the cruciform is sitting properly on the drop shelf.

In 30+ years of owning Glocks, I've never checked this. I bought the armorer's plate when I had aftermarket parts in a 17, but I never used it.

I can say, my 43X and 48 both of which have polished internals, Wolff fps prings, 5lb striker springs and Johnny Glock  reworked OEM curved triggers have less engagement than my RXM (gen 3 trigger assy) with  an Overwatch Precision trigger, NP3 trigger bar, polished internals and Wolff striker and fps sprigs and G45 6 with Wolff 5.5 striker, fps springs.
All 4 have Glock internals aside from springs, the larger guns have 100% engagement,  the slimlines have more than yours appears in photos? Maybe 80% but less than the large guns.Ive had similar curiosities. Maybe slimline tolerances?

After doing some looking, it seems like the slim lines tend to have less engagement, and this is fairly common.

Unload it and hit it front different directions with a rubber mallet. If the striker doesn't release I would feel comfortable carrying it.

I've done this along with all the basic safety checks on both slimlines, too bad I hadn't checked engagement right out of the box but, why would you, I have to assume that's the way they shipped from Glock and both are the same so it's not like one has an issue. They're solid and GTG.

OP all I have to add is Glock trigger parts seem to have a wide spec, and despite that - I've never heard of anyone having the striker slip using factory parts.

*IF* it did slip, it would hit the drop safety.

I know you know this and still a fair question but I wouldn't over think it.  This isn't an Sig we're talking about. You have to double check their engineers

Whenever I do a trigger part swap or mod, I have a list of things I check.  With this being my first slimline that I've ever tinkered with, I went through the same checks....it just threw me off a little bit.

I actually found that the kit that I bought (using all factory parts) had more engagement than all factory once I started swapping things around and trying every combo of parts that I had.

Long short, with the factory back plate installed, I cannot get the striker to slip off the cruciform, so all good.  But the reason why it was slightly of concern, I replace the striker block spring with a lighter spring.  I know it would take a ton of dirt and gunk in there to get it to stick, but I suppose in theory, it would be possible.  If the striker could slip, it would be something I'd want to rectify.  However, assembled with the factory back plate, it isn't going anywhere.

With only having one example, I figured I'd toss up some photos and see what everyone thought.  From digging around, seems like this is normal and it is what it is!

Have you ever looked at engagement of GPT?
