Failing to go into battery

[Guest CK1]

Failure to return to battery doesn't always mean you need a stiffer spring, in fact, in a new gun with a fresh spring it can mean you actually need a lighter one to get the slide-speed up. An 18.5lb recoil spring is pretty stout, definitely stout for WWB or any reloads that feel around the same PF, most competition shooters run a 14#, so you might want to maybe try a 16# and see what you get, remember that a lighter one will usually feed better, shoot flatter and tend to tame the recoil, NOT heavier as many mistakenly believe.

Mainspring weight matters and plays a role too, most stock ones are between 19#-23# so you should be just fine.

Also, despite what you may hear by going lighter, frame-battering is of no real concern unless you plan on running 1000+ +P loads through it on the same spring or decide you want to run as low as an 8#-10# (some do as it shoots really nice with softer reloads).

Had Jeff at Hero look at it and it was the spring. Said it was like an inch too short or something like that. Running the same spring they use in their 1911s now and it is smooth as silk.
