I need to order some parts for an older 90 degree breech 2nd gen G17 and I'm having trouble figuring out just what to order. Several of the parts I need are very confusing concerning the models they'll fit. Figured my best bet might just be to get together with an official armorer. Does anyone know one who operates locally? If so, I'd appreciate being put in touch with them. PM is fine, if you think they'd rather remain UTR. Thanks in advance.
