Echo 1 proudly introduces the Timberwolf designed and licensed by Lone Wolf Distributors. Among the improvements are a choice of 2 quick change grips, rounded trigger guard, extended beaver tail, round mag catch, improved checkering, higher grip angle and an improved rail system. Moreover, many claim it is better than any double stack 1911 offered! Install the swelled grip and try to decide, is it an XD or a Sig. Either way, it takes less than a second to try them both. Enjoy this great invention and play safe!
