You can get replacement frames from Glock? You have no idea what you are talking about!
1 Glock Inc (GI) does NOT sell frames to "Joe Blow" so he can build a custom gun.
2 When GI does make a frame available the price is NOT $40 to $50.... more like $175 plus.
3 WHY on earth would you purchase a replacement frame from GI for another JUST like it? The Lone Wolf frame has MANY features the GI frame does not. For that matter, the LW frame has many features a CUSTOM reduction CAN NOT compare to.
