SA 1911 Range Officer

I need to replace the firing pin spring in my wad gun 45 ACP Range Officer. The only replacements I can find are Extra Power springs. What are the recommendations for replacement of the original spring?
Is EP spring ok as a replacement? Are original springs EP?
Thanks.

More qualified gunsmiths should be along to answer this in short time, but in my experience, when I first started shooting a 45 I had a SA RO. It didn’t work out for me and I quickly commissioned a wad gun built out of a SA Mil Spec. But when I had the RO, I used a reduced power hammer spring in conjunction with a reduced power recoil spring. The reduced power hammer spring, plus a light weight firing pin that SA uses, plus a heavy firing pin spring, did not work well. I had lots of light strikes. I switched to a steel firing pin of correct diameter for the gun, and a standard weight firing pin spring. These parts worked well with my reduced power hammer spring. At least this is what I recall. Again, I shortly commissioned a real wad gun, and the RO was transformed into the lower that my Nelson rides on. And I still have my Nelson and that lower combination today. Hope this helps.

I just replaced the Ti firing pin and spring in my RO with an EGW 0.075" o/s firing pin and used the extra power spring from one of my Wolff recoil spring packs. Just ran 150rds thru it with no issues at all.

Over the years, every time I order a recoil spring it also includes a firing pin spring which I assume is standard power.  Therefore I have several of them and will send you one if you'll send me you address.

Hi Phil,
I really appreciate your help.
I ordered a standard and XP set from Wolff just in case.
I’ll put the spring in I ordered and will try them; if it doesn’t work I’ll reach out to you.
Thank you, again!
Have a great Memorial Day!
