My nib 45 hates my reloads. I'm using 5.1grs of wst and a 200gr bullet and every round is a failure to eject. This is the same recipe I use for my Kimber 1911, sig 220, smith 4516, and smith m&p 45, and don't have problems with those guns. Put factory ammo through gun and gun runs perfect. I looked on Wollf's web site for a lighter spring, but they don't list springs for the fn's. Should I try different powder or shoot it with factory till the recoil spring breaks in some more?
I have about 500rds through the gun |
| Are you using wad cutters or flat point ? I run 230gr roundball plated and lead with 5.6 grains of Winchester w231 and have never had a hiccup in my fnx45 or my 1911's , Kimber & Ruger, maybe check your COAL and crimp to be safe, I think my oal is 1.270 & crimp is .470, good luck, you will find the sweet spot. |

i also had a similar problem with my FNX45. It would only cycle at just below max powder charges with a 200gr RN bullet. I read about using a modded G17 glock spring that would cycle target loads better. link here There was no confirmation that it did work and they were talking about the FNP45.
Before I messed around with the spring I was going to lock my slide back for a couple of weeks. Right now my slide it also locked to the back going on week 2. |
