The RSA rating for Glock G19/23/32/38 compacts should be

The only Glocks with a

How did you get 11 likes off of 3 posts? Is that really a picture of you?I have a new G19. I've put about 400 rounds through it. I measured the recoil spring and found it to be 13lbs! I thought stock spring was 16lbs? Any ideas?

Thanks for your helpful reply! Yes, Gen 3 model 19 (and yes, California). I thought spring rates were measured through only one inch of travel. I'll remeasure the spring force using the distance you described.Gen3G19.

The RSA rating for Glock G19/23/32/38 compacts should be18-lbfwhen compressed by the slide as far back as the slide will go. How did you measure the compression, and was the slide at that point on the frame?

The only Glocks with a16-lbfRSA rating are the G26/27/33/39 subcompacts.

The RSA isI thought spring rates were measured through only one inch of travel. I'll remeasure the spring force using the distance you described.

The spring constant

If you measured the force of the RSA as 13-lbf after 1 inch of compression, you have measured the RSA spring constant

The force exerted by the RSA at full retraction is its rated spring force. That depends on both the spring constant and the distance of maximum spring compression or slide retraction.

I don't have any Glock compact models, but I'm pretty sure that the length of slide retraction is somewhere around 1.4-inches. Then for your RSA:

Spring Constant (measured by you) is 13-lbf/inch.

That agrees with the advertised Gen3 G19 RSA spring force of 18-lbf.

You could measure the force at full retraction to verify these results directly.

Is RSA "Recoil Spring Assembly"?The RSA isnotrated inunits of force per unit distance of compression. It is rated only inunits of force.

The spring constantkmay be expressed asforce per unit distance of compression, orlbf per inch(lbf/inch), but the parameter of interest is the total force (lbf) exerted by the spring at or near end of travel.

If you measured the force of the RSA as 13-lbf after 1 inch of compression, you have measured the RSA spring constantk,notthe RSA rated spring force.

I don't have any Glock compact models, but I'm pretty sure that the length of slide retraction is somewhere around 1.4-inches. Then for your RSA:

Spring Constant (measured by you) is 13-lbf/inch.

Spring Force(calculated by me) is 13-lbf/inch times 1.4-inches =18.2-lbf

That agrees with the advertised Gen3 G19 RSA spring force of 18-lbf.

You doubted it?So I measured the amount of compression that my recoil spring undergoes during a full slide rack on my Gen3 G19. I got approximately 1-7/8 inches. I then put the recoil spring back on the measuring jig I made. It took a little over 17lbs of weight to compress the recoil spring ~ 1-7/8 inches. So I guess I'm satisfied that stock Glock Gen3 G19 recoil springs are "18 pound springs". :winkie:

FWIW, the Glock pistols are a fairly simple system, and as long as the gun is functioning properly and specified parts are being replaced at the correct interval (the Gen 1/2/3 RSA is around 3,00 rounds) then the recoil spring is operating properly;

Also, there is a simple (non-firing) function check for the RSA that allows you to make a quick determination as to whether the RSA is OK......

Forget about it. It works, forget about it.
