.45 Super Ruger P90?

[concrete]

I have come to the conclusion that it would be easier to convert my .45ACP pistols [Glock 21 and Ruger P90] to be able to handle the .45 Super load, rather than my original plan of trading for a Glock 20 10MM.

I do not reload so I would be forced to get either 10MM or .45 Super rounds via the Internet.

I believe that Glock 21 with a 22# spring (Wolf) does it for the Glock, but how about a Ruger P90? What modifications do I have to make to allow the Ruger P90 to shoot .45 Super safe and reliably?

Anyone that has experience on this subject, please share your advice/opinions.

Thanks.

Well the Ruger probably is the right pistol for the job. It's not generally known, but the .45 Rugers WERE designed to be made as 10MM pistols also, for full power loads like the G20.
In come the bean counters & decide that the market % isn't enough to justify it, so the 10MM versions are scrapped.
FWIW, at least 1 of the Ruger prototypes was set up to use a G20 15 rd. magazine. This is a belivable fact from a friend who used to be involved with R&D at Ruger & still works there, but now in a higher capacity!(sorry about the pun...wasn't intended)

Thanks for your input. You are actually the 2nd person that has enlightened me about the Ruger P90 originally planned out to shoot 10MM. It sure seems big & bulky enough to handle it.

Do you think you can ask your buddy at Ruger the .45 Super conversion question? Is stock spring weight enough?
It may very well be already prepared for the job.

Thanks.

Since there is .45 Super ammo out on the market, I do know that the R&D boys have tried it. I'll e-mail & see what is recomended for the change.
Of course the reply will be "unofficial", but WILL be informative.

Got a reply from my friend in R&D....not good news.
Since Ruger decided to not go the 10MM route, basicly the P 90 is a dedicated .45 auto. Reason; Slide is too light & more spring won't cure that. Timing is set for .45 & .45+Ploads, failure to feed with the faster slide impulse is a distinct possibility. To quote "You won't blow it up, but you WILL beat the snot out of it".
Won't do much for operator comfort either.
sorry 'bout that.

suggestion...Get a G 20 & live happily ever after. The .45 round started life as a 18,000 psi load & most guns are in this ballpark. The 10MM started life as a 40,000 psi load, since neutered by SAMMI to about 34,800 psi. Some lots of the old Norma 10MM averaged about 43,000 psi. This is in serious magnum territory, up with the (earlier).357,.41, & .44 magnums,(all 3 recently also neutered by SAMMI) The G 20 will take the constant pounding. My oldest G20 (KONG) has well over 15,000 rds of hot & hotter ammo thru it. It's only failure to feed came from MY foolish attempt to shoot "gamer" loads in IDPA. The G20 likes it's ammo HOT & shoots to best accuracy with potent ammo. Suggest if you don't load, check out Mike McNett's "Double Tap" brand. You won't be dissapointed.

I think you will find cobalt bits will cut that hole very fast and clean use constant presure and cuting oil do no stop till thrue it sounds like the materal is work harding

Looks like MMurray got his threads mixed....he should be on the "drilling a Glock triggerbar thread"
That's where we were talking about cobalt & carbide drills.

Thanks for the info. It is Greatly appreciated.

I just figured if I were to convert my G21 to shoot .45Super, might have been a slight chance the P90 could do it as well.

Oh well, I guess I will just have to work a little harder and try to get that G20 I was initially looking at into my hands. :cool:

Thanks again & stay safe!

u.a. I couldnt have put it better myself.You also would be hard pressed to find an aluminum framed 10mm,if any exist they slipped under the radar.Full juice 10mm loads would wreck the P-90,and it wouldnt take long.Had Ruger ever designed a 10mm,it would have probably rivaled the Desert Eagle in size.

[VN350X10]

Actually, there were/are about 6-8 .45 frame Rugers in 10MM, as it was designed to be a similar platform to the Glock 20/21. One or 2 of the guns are setup as wide bodies & use Glock 20 magazines!
The bean counters killed the project, not the engineering boys. The slide would of course need to be heavier than the .45 version, but little else would need changing.

Overall 10MM sales in the industry (or LACK of) were the push that really killed the project.
