If you desire a Glock "type" 1911 then Wilson is about as close as it gets.
SPEC-OPS 9
A polymer framed carry pistol with a proven 16 round metal magazine, 1911 style fire control system, completely new barrel lockup and reengineered recoil system scaled for the 9x19 cartridge-all under 30 ounces unloaded. Add Wilson Combat's legendary heritage for steadfast quality and you get the perfect high capacity 9mm for range or street with the following cutting edge features:
• The unique, mid-length, reduced mass slide design generates minimal muzzle flip with any 9mm loading and is trimmer in every dimension than a standard 1911 slide. Angled front carry cuts enable easy reholstering and press checking while adding a distinctive custom profile.
• The all new, premium grade 416 stainless steel barrel with enhanced lockup geometry is ideally matched to the recoil impulse and pressure of even the hottest 9mm loading. The SPEC-OPS 9 chamber area has been likewise strengthened and the muzzle smoothly interfaces directly into the precision bored slide without the need for a separate bushing.
• The stainless steel frame rail assembly is CNC machined from solid billet steel to exacting dimensions and permanently fused to the polymer grip for unfailing, precise rigidity. Unlike other polymer 1911 style guns, this grip is guaranteed to never come loose when you least expect it.
• The SPEC-OPS 9's Kevlar and Zytel reinforced polymer grip has Wilson Combat's popular Starburst pattern molded in for the perfect amount of traction in varied conditions and enhanced concealed carry comfort over traditional grip designs.
• A reduced profile grip safety tang and unique, matching hammer reduce the concealment footprint profile of the SPEC-OPS 9 over a traditional 1911.
• The SPEC-OPS 9 retains the extensively tested Wilson KZ-9 16 round double column magazine for ultimate in 9mm feed reliability. The tapered magazine ensures rapid reloading under stress.
• The new low-profile sighting system is perfectly scaled to the SPEC-OPS 9 slide's reduced width and height. The front sight is easily end-user removable from its longitudinal dovetail.
It doesn't have a radial lug in the 1911 sense. The upper part of the chamber locks in the front of the ejection port (Lug 1) like a Glock. You have the 2 lower lugs like a 1911 (lug 2) and also an oversized breechface/hood area (lug 3). All are fitted for a solid 3 point lockup.
