Thanks for the info.

Joe4d - I do understand the design. I did not however separate my thoughts when posting. The recoil issue is one issue and is simply the stock spring in combination with the comp. Stock ones range from 12-14lb. The firing pin spring and main spring have to do with, as you mentioned, slam firing. It's a series 70 and they will on occasion do that. Mostly if someone puts a round in the pipe and drops the slide stop. The series 80 solved that issue with the firing pin block safety. The ejection drops the casings at the shooter's feet. It's a Valkyrie break and slows the slide down, hence the need for the lighter recoil spring. The chart posted on this site elsewhere suggests a 9lb with a comp and higher without. Either is lower than stock. The bushing is fine, there is no binding, grinding or hinderance of any kind. It operates as a bushing perfectly. As for the Comp and whether or not it's ridiculous, isn't mine to say. The customer gets what the customer wants. It's not my place to pass judgement on their wishes. I just make it work. And you folk are competition minded folk, I thought to inquire here in hopes of words of wisdom. What I've gleaned thus far is that a 9-10 lb recoil spring will solve the issue. I fired a mag thru it this AM and had zero malfunction, however the casings landed near my feet. With the extra weight and doodads it felt like shooting a 22. So the break is doing what it's designed to do. Being aluminum, it really adds no weight. I don't personally recomend the aluminum against steel as it wears faster. But this is not a compitition gun. It's just for plinking. So... why do people want the compensators and all the fancy stuff. Blame John Wick for that one.

They are customer supplied parts. Only fitting was the safeties and trigger. Rest were drop in. Everything was fine before the break was installed. It was drop in as well. The springs are all stock. On other guns I've gone lighter on the recoil, heavier on the firing pin spring and heavier on the main spring to get optimal performance. The comps I've installed haven't needed any spring changes. The break I feel is slowing the slide down, and preventing complete cycling. According to the chart a 9lb should solve it. Being an A1, I feel like I should change the pin and main springs as well. Mainly because there is no firing pin block safety.

Thanks for the chart in in that thread. Thought I'd start a new one for my question. I'm pretty sure a 1911A1 in 9mm comes standard with a 12lb recoil spring. The gun now has a muzzle break on it and has occasional misfeed and stove pipes. Probably 10% of the time. Cycled fine before. I'm guessing a 9 lb spring would fix this. Does this indicate the need for a heavier firing pin spring and main spring as well?
