The glock mounting plate basically replaces the rear sight of the handgun. The rear sight dovetail is exactly the same for all glock model, therefore this plate fits all glocks from glock 17 to glock 43 to glock “100”.
It will fit： G17/G17L/19/G19X/20/21/22/23/24/25/26/27/28/29/30/31/32/34/35/38/37/39/41/42/43/43X/45/48 they all use the same rear sights
