2011 magwells — aluminium and brass
Magwell choice shapes reload speed and frame balance. Aluminium magwells are USPSA Limited and IPSC Standard division-legal — minimal added weight, maximum funnel. Brass magwells add 4-5 oz of bottom-end weight that flattens the dot in Open division and Limited Optics. Both bolt straight onto STI, Staccato and Bul Armory frames.
2011 magazine base pads
Capacity wins matches. Our 2011 base pads cover 9mm, .38 Super and .40 S&W in standard, long and open lengths. Brass and aluminium options match your division: aluminium for Standard / Limited weight class, brass for Open and Limited Optics where bottom-end weight is an advantage.
Red dot scope mounts and optic systems
Red dot scope mounts for the 2011 demand precision. Our STI / Staccato red dot mount accepts Shield RMS, RMR and Vortex Venom footprints, integrating your optic without shifting zero. The Bul Armory 2011 Open red dot mount fits Bul-pattern frames specifically.
Extended controls — mag releases and thumb rests
Extended magazine release buttons drop reloads cleanly under match pressure. Slide stop thumb rests do double duty — they index your shooting hand for consistent grip and release the slide without breaking your firing position. Both are direct-fit on 2011-pattern frames.
Progressive recoil springs and drive system parts
Tune the 2011 recoil curve with a progressive recoil spring matched to your division: 8-10 lb for Open major-PF, 12-14 lb for Limited .40, 11-13 lb for Carry Optics 9mm minor. See the progressive recoil spring tuning guide for spring rate selection by division.
What fits this collection
Parts in this collection fit STI / Staccato, Bul Armory, SVI, Atlas and most 2011-pattern double-stack frames in 9mm, .38 Super and .40 S&W. Always check fitment notes on each product page for compatibility with your specific 2011 build.
