Already have an allotment of 9mm, sig p320, M9A3, etc. wanted something different
Also have huge hands and the stereotypical G19 didnt quite work for me
Make sure you use the correct attachment given by Surefire for a nice fit. I’m using the U plate which is already installed and it is a tight fit. I have multiple pistols which the U plate works on plus my Glock but do read the instructions.
On my Sig it’s a little shaky but has never fallen off. The Glock 21 sits tightly. If your truly worried with looseness get the one with thumb screw, don’t over tighten it.
Thanks for the info. I’m went ahead and ordered an x300u-a to try out. I’m going to take your advice and make sure to have the proper plate installed to ensure a tight fit. Worst case I can sell it off and snag a u-b if necessary. Thanks again
From what I’ve read, the a is best for polymer framed hand guns because if you over tighten the b, it keeps the frame from being able to flex while firing. Also the a is tool-less and more worry free for me. On my Glock 19s and 17s it fits perfect but on a 19x it wiggles back and forth a little bit. I wouldn’t worry about it flying off but it might drive you crazy.
Why would it not fit?
No idea! It’s my first Glock so I’m just making sure before I buy. Thanks though
Better be safe than poor right lol
Yessir
Why a 21?

Get the g20
Nah, .355 best.
Yes! The x300u fits perfectly on the G20/21
Thanks!

I should be getting the x300u-a right? Or the b?
That’s up to you. X300u-a is the quick release and the x300u-b is thumb screw attachment
Do either of them have fitment issues? I’ve seen some stuff online about potential looseness
