It's probably not the bolt catch.
Your gas system or recoil system or both.
Can you lock it back manually?
Will it lock back if you pull the charging handle back on an empty magazine?
The one on my jeep does that every once in a while. If I go into the menu on the settings there is a place to release the parking brake for brake service. That usually releases it.
My Sig365 has night sights that I can pick up pretty well day or night.
I put TFO's on about everything else I carry. Bright dots day or night.
The 365 fits in my pocket well and has the best trigger for a striker fired pistol I have come across.
Glad to help. I didn't order any this time cuz I counted what I have put back. I have 3 Grendel's and over a thousand rounds for each one. I think that will last a while. Especially if I would get off my butt and reload some of this brass.
