Looking at these to put a G19 mag into a G26, G21 mag into a G30, ect to make the grip more stable.
How good are these sleeves? Any issues/hangups inserting the mag?
I use XGrips on my Glock G27 and HK P2000SK.
They have been flawless for me.
For the baby Glocks there are two sizes.
Size 1) G26 using a G19 mag
Size 2) G26 using a G17 mag
Make sure you're getting the right size for your application.
