will a guide rod from aGlock model 19 fit into my sd9ve,I was told it would if anyone has tried this please let me know they are half the price of a sd9ve.

Got look at that I got a glock rod...but don't think so

Nope different glock just hair longer.. Just compared them

It will work just fine. A G19 has a 4inch barrel just like the SD9VE. Look on Amazon even at the G19 guide rods and you can read lots of reviews of people buying them for there SD9VE and saying they work perfect.

Well o got a new guide rod for a 19... And I compared it to my sd9ve and it looked different was a little longer but if it works so be .I wouldn't use it ..best bet get a factory one or after market stainless.. That's my two cents

This is a common mod and apparently produces slightly less muzzle flip because of the difference in spring weight. I believe there are YouTube videos demonstrating this.

I have never shot it this way but I have put my Gen3 G19 rod in my SD9 and it functioned just fine while manually cycling and dry firing. I imagine it would be just as reliable as any aftermarket recoil assembly. That being said I tend to just stick with OEM.

Have you fired the sd9ve with the g19 guiderod in it.and if so did it seem to act ok.

Yep like also to know

I have replaced the stock guide rod with a Glock 19 guide rod and the gun performs perfectly. It fit the SD9VE and functions as advertised, at half the cost.

What are the spring rates and installed force for the S&W and the Glock?

I purchased mine from Galloway Percision and stayed with the 17# spring. Works well over the last 3-400 rounds and at half the cost. I did not have any failures with the factory set up, just wanted the extra weight up front.
Modifying a firearm is the responsibility of the owner and I accept none for this recommendation. So far my mod has served me well and I have had no failures to feed, eject or fire.

That extra weight does make a difference. I have a tungsten guide rod in a Glock 21 and it went from a push to a puff when shooting.
