I highly recommend getting your information from the experts at Boss Components. Using an incorrectly weighted spring can cause firearm malfunctions and create a serious safety risk, particularly for novices. The Boss Components spring works perfectly, and I was very impressed with their service and fast delivery.

Love the feel of the progressive springs, soft start but tightens up enough to handle loadd nicely

Bought several progressive springs from Boss Components for my Staccato XL (2011). The problem I was trying to solve was misfeeds with the factory spring (7 lb) when using low muzzle energy 9 mm ammo, specifically 147 gr, 900 fps rounds. The BC 7 lb (nominal) progressive spring solved the problem. Note that the factory spring measured 7.5 lbs at full travel while the BC was 10.5 lbs, much better at closing the slide. The progressive spring basically acts like a 7 lb spring in terms of felt recoil, but reliably closes the slide, more like a 10 lb spring. Solved my problem without noticeably increasing the felt recoil. For 2011 shooters, note that the barrel ramp is steep and builds up carbon quickly. Flat head rounds (e.g., Syntech) are especially prone to "stick" to a dirty ramp, which causes misfeeds. Other causes are riding the slide with your thumb and of course a spring that is too weak.

I like the design of this spring and the feel of my S2 recoil impulse. I am currently using the 12lb progressive spring with the Boss tungsten guide rod. The slide closes a little more slowly than I am used to, but I havent had any malfunctions with factory Blazer ammo

Experienced some difficulties with my new 1911 in that it would fail to chamber every half doz rounds or so. Initially looked at the feed ramp, mag lips being distorted among other checks. Finally came down to the recoil/return spring which I thought may be the issue. Research and source Boss Components for the remedy in the form of the 16lb spring. Have managed to get some rounds away and the spring is working flawlessly. No hang ups and a solid return to battery. Will get a better idea with more rounds but so far I am very pleased with the spring and looking forward to participating in a few comps. I have purchased a 17 & 18lb spring in reserve should I need a boost. I have 2 x 1911's so now well prepared when I start on the other. Much Thanks to BC for your assistance in my endeavours.

Molla 10lbs progressiva con la KMR Umbra perfetta, palla 125 FMJ , colpo morbido e ben gestibile che permette una buonissima velocità di tiro !!! La stessa molla con la CZ Shadow 2 e l’asta guida molla in tungsteno, l’arma rimane perfettamente allineata e permette una maggiore velocità di split .. Consiglio !!! TOP!!!

The progressive springs are amazing even if they say they are for the shadow 2 i’ve been using it on my Tanfoglio Stock Master Xtreme and it works like a charm i got the 11 and the 10 lbs springs depend on the ammo available and they both do magic
