LONE WOLF R&D LLC MODEL TWL1, .45 ACP, 1 MAGAZINE - 13 ROUNDS WITH A 4.38 " LONE WOLF BARREL. THIS PISTOL TAKES AFTER THE GLOCK 21 AND IS IN VERY GOOD CONDITION WITH SLIGHT HOLSTER WEAR AND COMES WITH A SOFT CASE. The Lone Wolf Timberwolf Large (TWL1) frame is an aftermarket, ergonomic upgrade for large-frame Glock pattern pistols (Models 20, 21, 40, and 41, 21 in this case). It is designed to replace blocky factory frames with a slimmer, more 1911-style grip angle, and includes an interchangeable backstrap, an extended beaver tail, and an undercut trigger guard. *****Reviews & User Consensus***** ***Ergonomics (Consensus): Users agree that the biggest selling point is how it feels. Shooters with smaller hands report being able to easily manage and control the heavy 10mm and .45 ACP calibers, which often feel unwieldy on standard factory frames. ***Reliability (Consensus): Once properly built, users experience fantastic reliability, with many noting that all OEM and aftermarket Glock parts drop directly in without issues. ***Value, it is widely considered an excellent value, though availability fluctuates. *SPECIFICATIONS* Manufacturer: LONE WOLF R&D LLC Model: TWL1 Caliber: Magazines: Sights: Weight: Overall Length: Barrel Length: SERIAL NUMBER: SKU NUMBER:
