I'm kicking around the idea of buying a G17L. Only because I don't have one! Found a real nice one on GB that has my interest. I won't be bidding on it or making the purchase for a month or 2. My question has to do with the frame. Is it a standard 17 frame? From what I've gathered the only difference is the barrel and slide length. All other parts including the recoil spring assy are interchangeable. Are they still in production? I'm guessing not as they are not listed on the Glock web site. I was going to wait until the 4th Gens are out and get another G17 but I'm really not gaining anything with the changeable backstrap as the standard G17 fits my hand just right! I may end up buying one eventually but the G17L has my attention. Chime in with advice!
