Hey guys,

I took my revolver (I'm new to revolvers) out today, SW 19-4, and had light primer strikes. Same ammo I have used before (Fiocchi 38 special) without issue. First time I've show it in the cold, but I have a hard time thinking it was the temps fault.

I was doing some reading online and people keep talking about checking the strain screw. Like I said above, I am new to revolvers. What is a strain screw?

Also, any other advice or tips you have for this issue lemme know. Thanks homies.
