Pretty much any Walther gun is lefty friendly, i know im lefty, i have the P22 the PPS 9mm and the PPQ 40.love the mag release location on Walthers,i want a p99 but havent gotten one yet. Soon

.
Not a glock fan, very thick weapons and not lefty friendly, i do have a sw sigma 9mm and its not lefty gun but i learned to release mag with my left hand middle finger and release slide with my left pointer finger, lol works just as fast as if i did it normally w right hand,im lucky i can shoot very well with either hand, being lefty in a right hand world makes us leftys very ambi. Walther pps is awsome for carry and lefty, highly rec it
