Recoil Spring Question

[GigaBuist]

Yeah, I retract what I said earlier. My bad. I was looking at it all wrong.

Taken to the nth degree, a solid spring, you would probably drop the gun after the 1st shot

That's actually the model I was using in my head when I posted my original comment. If you had a recoil spring (or a solid bar) that prevented the slide from moving at all you'd feel like you were shooting a revolver. Most folks don't drop them.

Maybe it's on a table, a chair, but not the ground..

And another thought about Springs and recoil.. Ever see a car with stiff, strong, springs.. Really doesn't absorb bumps, it's stiff and bounces, as opposed to normal springs/shocks, that have a much softer, less stiff, ride, absorbing the bumps in the road, sparing the occupants head hits off the ceiling..

I really don't think you'd drop the gun without the recoil spring. I've never dropped a .44 mag or my pistol-gripped 12ga. I've also never dropped my S&W 1917 revolver in .45 acp (that I shot in a match yesterday).

Felt recoil is largely a product of weapon design and weight. My 24-ounce .45 kicks a lot more than my 38-ounce.

I have two that weigh 38 ounces and the one with the lower barrel axis (CZ) has less felt recoil than the 1911.

I've never fooled around with recoil springs except to improve reliability or function. If a gun is uncomfortable to shoot I first check how I am gripping it. If my grip is correct and I can't resolve a felt recoil issue (which has rarely happened), I look at new grips.

Grips are also the first place I look when I have a problem shooting a gun accurately. I almost gave up on a SIG P220 but a friend of mine shot it really well. I changed to Hogue finger-groove grips and it's a tack driver.

My personal experience is change springs for performance. Change grips for comfort or to improve consistency.

Just my 2 cents....

It's been my experience that revolvers have a higher bore axis, and tend to create a "recoil spring" from the shooters hand and arm.

Well here is the Range Report I went shooting on Saturday after I went to the local gunshow were I picked up 500 rounds of Wolf 40SW and 50 rounds of surplus 7.62 x 54R and 100 rounds of Georgia Arms 5.56 and a extra magazine and a Hogue Grip-All for my SW Sigma I got it all for about $190. I got to the range and I had the extra power recoil spring in and I once I fired the first round I had my first Fail To Load with the pistol so I put the next round in the chamber it fired that round and then Failed to Load again so I put the next round in the chamber and fired I had another Fail To Load so I cleared the pistol Field Stripped it and put the stock recoil spring back. After I put the stock spring in it, it fired perfectly then, with the Hogue Grip-All grip and the Trigger job I did it was amazing I was able to fire about 200 - 250 rounds with out getting too sore. It still is not a pistol that is able to get a great groups at 35 plus yards but I am able to get decent groups at a range that I would feel comfortable engaging someone if I should ever have the need to, and with more practice I am sure that I can get better groups. I am very pleased with this Pistol and would recommend it to anyone

And I thought only CZs had extra unneeded parts!

Taken to the nth +1 degree, suppose we remove the recoil spring (zero resistance) beside breaking the slide stop, and maybe your wrist, how would pecieved recoil be then? ( meant for humor...not meanness)

Ned Christiansen did that very thing...firing the gun repeatedly with no ill effects. The slidestop doesn't stop the slide in recoil...only as it returns to battery.

Many don't understand that firing the cartridge in an autopistol doesn't generate much of a recoil impulse to the shooter's hand the way that a fixed-breech gun does...like a revolver. The recoiling assembly...slide and barrel in a locked-breech pistol...well...slides on rails with little resistance except for the spring, and when the slide strikes the impact abutment.

Felt recoil comes mainly from the compressing of the spring. Impact causes muzzle flip. The faster the spring is compressed, the sharper recoil will be.
The heavier the spring is...the sharper the recoil will be.

Why?

Because the recoil system is a closed system, and once in motion, sets up its own action/reaction event. The slide is one side of the equation. The frame is the other. The compressing spring adds a vector of force between the two. As the spring compresses, it imposes a forward force on the slide, and a rearward force on the frame...and there you have it. Newton 3 in action.
