WarBoom Posted July 3, 2020 Share Posted July 3, 2020 I have a Stock 2 large frame I use in CO. Im looking for a 22lr conversion so I can use it in Steel Challenge but I can only find the small frame 22lr conversion online. I've read the only major difference between L/S frame is the lower/grip area. So, will the small frame slide conversion fit onto my large frame? If it will, would I only have to buy large frame magazines? thanks. Link to comment Share on other sites More sharing options...

Maurice Posted July 3, 2020 Share Posted July 3, 2020 I have 1 for small frame, it is a pita to make reliable. You need to use a heavy hammer spring too. Link to comment Share on other sites More sharing options...

Sent from my iPhone using Tapatalk The trick to getting it to cycle is 40gr high velocity ammo, 37gr doesn't work as well if at all. As Maurice mentioned you may also get light strikes if you run a light hammer spring. Link to comment Share on other sites More sharing options...
zombywoof Posted July 3, 2020 Share Posted July 3, 2020 (edited) I have one I use in my S2. I can run standard velocity 40 grain ( I have lots). Federals ignite nice, Aquilla not so much needs a HEAVY hammer spring. Lots of fun. Mine runs nice. Make sure it's lubed good and moves smooth.

WarBoom Posted July 3, 2020 Author Share Posted July 3, 2020 I use a 14lb hammer spring.In my gun the pull weight difference between a 10 and 14 was only .3 lb I’d rather have reliable ignition than a slightly lighter pull.

WarBoom Posted July 3, 2020 Author Share Posted July 3, 2020 Let’s hope the 14 is heavy enough Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
canbuster Posted July 19, 2020 Share Posted July 19, 2020 (edited) @WarBoom, let me know how 14 lbs is working out for you. I just switched to 13 lbs on my small frame and have not shot it yet Edited July 19, 2020 by canbuster tagging WarBoom Link to comment Share on other sites More sharing options...

I just switched to 13 lbs on my small frame and have not shot it yet had to use the factory spring to prevent light strikes. I did my best to use the 14lb first. I lengthen the firing pin stroke by .015 by cutting the shoulder lengthen the set back by .020 removed the firing pin block polished the rails and pin channel swapped the pin spring with weaker Best I could get was 8/10 fired with various ammo. swapped to the factory and never had an issue. Shoots great. Link to comment Share on other sites More sharing options...
canbuster Posted July 31, 2020 Share Posted July 31, 2020 Ok the 13 lbs hammer spring is no good, only ignite 5-6 out of 10. So back to the factory spring Link to comment Share on other sites More sharing options...
Dan4147 Posted January 21, 2021 Share Posted January 21, 2021 Thank you guys for the info. I have a 45/22 conversion that I finally have time to run the 22. Everything is smoothed and polished and I am still getting the same light strike results as above, with the 14-15 lb hammer spring that I had in for the 45. So, I will try the heaviest spring I have. If that isn't 100% I will try the fp mods as above to increase momentum. Link to comment Share on other sites More sharing options...
Dan4147 Posted January 22, 2021 Share Posted January 22, 2021 So I put the stock 45 hammer spring back in with the 22 conversion. I think that spring must be about a 24lb. Shot a few mags of the various ammo, cheap bulk, up to mini mag. Everything went bang, no light strikes. I was worried that the hammer might slow the cycle but everything fed. So, confirmed those that said the hammer spring is the answer, at least on mine. Link to comment Share on other sites More sharing options...
zombywoof Posted January 23, 2021 Share Posted January 23, 2021 I have a DPP attached to the top of mine. It still cycles. Link to comment Share on other sites More sharing options...
