Question SR40 to SR9

Hi new guy here with a quick question.

Will a SR9 slide or barrel fit on a SR40? I've been thinking about it but couldnt find an answer. So if you own both could you try it? Thanks.

I wouldn't think so, have you contacted Ruger? It's free!
Even if you can get the slide to "fit" Chambering a round could be dangerous or even fatal.
You definitely need Expert advice. Ruger or a certified gunsmith. Not just Joe Blows opinion.

I hope to see a second post from you, that way we know that you are not mortally wounded or worse.

Switching calibers

I can't answer your question about the Rugers in question, since I don't have those guns. However, in sort of an oblique reply to your question, I have a CZ 75B (.40) that also came with a fitted 9mm barrel. I can switch from shooting .40 to 9mm (and back, of course) by simply changing out the barrel and magazine.

I bought this rig a couple years ago through an online ad. Prior to this purchase I didn't know that you could do such a thing in changing calibers like this. This has turned out to be a fantastic acquisition for me, and I'm lovin' it!

Happy Birthday, America!

In what I have seen in other guns a barrel change is all should need be done. This would work with 9mm Barrel in a SR40 only like Amistad said. Now Ruger might not have made it possible but it won't be long before someone like Lone Wolf or Storm Lake will have a drop in barrel threaded or caliber change. Here's a link to some aftermarket parts for the SR9/40, good luck. Oh and you could always lead the way and have a barrel made and fitted.

Gunny G, Another one of your worthless posts. I highly recommend ... if you don't know the subject matter, don't comment. The OP had a very valid question. We have a lot of "Joe Blows" on the forum that are very knowledgable .... then we have people like you that just like to hear the keyboard click.

Jgloveracob, The 40 S&W and 9mm slides are the same. If you are considering a conversion, all you need is a barrel, recoil spring, and magazines. Swapping slides may not work because they are fitted to the frame.

I know the SR40 slides are heavier but an SR9 Recoil spring should work just fine. I'm not sure the OD of the SR9 And SR40 barrels are the same. If they are, then most likely a barrel swap is all that it will take. Dimensionally they should be the same like Iowegan said. As for the magazines, you may be lucky. You may just be able to load 9mm rounds and go to town. The mags that came with my SR40 had 9mm followers in them. This works for the XD line of pistols. 9mm rounds work in the .40 cal mags with 100% reliability and with increased mag capacity. I'm still curious to see who here has both and can confirm a drop in barrel swap.

I am curious are the slides identical on the two. Only reason i ask is because the 40c slide is thicker and a heavery duty then the 9c due to obvious reasons. Not much but a trained or knowlegable eye can tell.

Just asking. I think tge 40c to 9c would require the whole top end switched out. Unless you are going from the 40c to the 9c.

But my 2cents would be play it safe get the barrel and slide better to be safe than sorry right.

Also i was thinking about trying to hunt down a 40c top end im a few months for the same purpose so im interested to see how this goes

I can't give a professional opinion, however, I bought a complete SR40 stainless slide and barrel off this forum. Put it on my SR9 lower, it performs flawlessly. Obviously, using 40 cal mags. Iowegan, comments?

If you go to the Galloway Percision site you will see that the SR9c and the SR40c both use a 16lb recoil spring, but the Sr9 uses an 18lb spring, and the SR40 uses a 22lb spring, so you would need a new spring as well as barrel. Of course that's if the slides and magazines are compatable. But that is an interesting prespect. The sig p250 series is interchangable like that and you can even change from full size to compact frames as well.

The S&W MP40 and 357 can be cahnged to the 9mm with just barrel and magazine. But you cannot go 9 to 40, 357

It would be great if we can with the SR9

Jesus!...... Don't sugar coat it. Tell us what you really think lol. These guys are right,the SR40 slide is 1/16" thicker on each side than the 9. If you try a SR40 in a 9 holster ,you will see the difference. It usually fits but it is tighter. The 9 uses a 18lb spring and the 40 uses a 22lb spring.(I think).

Ok, just to put this thread to bed, I have a SR40 slide, which I put on my SR9. Works flawlessly. Maybe I got lucky, but if you look at the SR40 and SR9 parts list, all the lower components are the same part#. The answer to the authors question is yes, the SR9 and SR40 slide work on the base frame.

2 Front Sight VS03220 SR40
3 Loaded Chamber Indicator KVS11001 SR40
7 Extractor VS01421 SR40 – blackened steel KVS01421 SR40 – stainless model
15 Barrel – .40 S&W KVS00610 SR40

42 Ejector VS00901 SR40

The slide and barrel must be factory fitted.
