had a couple of these. after a little fumbling, they worked as advertised. then had to shoot a half crate of ammo before i trusted them. the extra grip length seemed odd after getting used to standard. however, 20 rounds of 9s in my G17 gave me bragging rights. the extra grip length on my G26 interferred with the purpose of a pocket gun, concealibity, or so it seemed to me. had i started with these, i may not have known the difference. i put them away and after a few years, they were no longer available. i sold them for a very nice profit. i did not particularly like the guy i sold them to, so no feelings of giuilt. hope you like yours.
