A good friend that's a machinist and a really smart guy told me it's a good idea to dry fire your guns before putting them away to relieve tension on the spring being held back that fires the firing pin. I had never heard this, but it seems to make sense.

Do any guy guys in here have any pros or cons for doing this?

We were talking about long guns and not handguns if that makes a difference.

This has been talked about before. I'm in the camp that it doesn't make a shite either way.

I was always taught to store my guns with the bolt open or out for safety reasons. Can't dry fire it in that case. Never had any issues. I usually put the hammer down on my pistols when they are not loaded though.

Whether you do this or not, the physics of this belief is false. Springs are not damaged or weakened by being compressed for long periods of time.

I think you can do more damage by dry firing on certain guns that you doby leaving the spring compressed. A compressed spring does no harm...

This.

I dry fire my guns all the time but not to relieve any spring pressure.

Springs don't lose springyness by being tense.

Damage/wear on springs comes from using the springs. Sitting compressed or not does no noticeable damage.

I have snap caps & I'm not a metallurgist but it can't hurt.

That's what I was looking for. I know it doesn't hurt to dry fire my old 870, but didn't know if keeping that spring compressed for months at a time could make it lose it's springiness.

Anyone have any links that back up this claim? Or are any of y'all mechanical engineers or machinists like the guy that told me this?

This

The idea that compression wears out a spring is a couple decades old. You can load your magazines to full capacity...you don't have to dry fire your guns before putting away.

on another note...the more you use your magazines, the less reliable they become. I mark mine. I use old ones for practice and keep the new ones loaded up for defense.

Ditto. Have them for .22, 9mm, and 12ga for this reason alone.

Springs do "creep" and loose springiness over time. Do they loose enough to matter? Probably not in your lifetime.

They absolutely do loose tension though. Stressed metal creeps.

Point taken. I haven't with mine and don't plan doing it
