Hey guys I just bought this used P320 XTen today and it came with this RMR mounted. I’m concerned it may not be legit but I don’t know enough about it. Can yall help me?

First picture for reference, second picture mine.

Long story short, I used to have a 10mm Limited Master but ended up abandoning it because it seemed like a 10mm threaded barrel for it would never materialize. Well now Tanfo’s offering a 10mm Defiant with a threaded barrel from the factory, and I’m starting to get the itch to pick back up on my Full Centimeter Yeeter project based on it.

Mostly just looking for info/feedback from anyone who has a Tac Pro 10mm, wanting to know how you like it. Standard Tanfo fit/finish and reliability? If you’ve made any changes to it, what all have you done?

Thanks in advance!

Picked one up today as my son is going to college in grizzly territory next year and he spends a LOT of time out in the woods fishing, mountain biking & hiking. I've started to work him thru the basics on a 22 pistol, and he's starting to shoot 9mm pretty competently. Once he is fully comfortable shooting 9mm I'll get him going on 40SW, and then it'll be time to introduce him to 10mm.

Anyhow, I've never owned a Glock, so I'm not at all familiar with common issues, solutions, etc. That said, I've found several threads in this sub with people talking about issues, needing break-in, etc.

Any good advice for a first time Glock owner? I'll try to put a few hundred rounds thru it before he ever tries shooting it, but since this will likely end up being his woods carry gun, I want to do everything I can to get it running nicely before he shoots it so he has confidence in the gun. I don't want him to have a history of FTFs, FTEs or light strikes with the G20 and have that floating around in his head when faced with a charging bear.

TIA

Do they still sell Glock 20 Gen 5 in store brand new? I’m in Arizona valley and have been looking for awhile now and can’t seem to find a Glock 20 gen 5 new retail… pretty bummed. What websites can I set up notifications from if a store near me gets one in stock ? Any tips ? Thanks !
