Bought the bullet. Was able to work out a favorable deal with a local gun shop. The 1006 went to them and a GP P40 is on its way to me. Would have preferred the P40L, but after many phone calls could not find a distributor with one in stock.

Will probably pick up a .40 S&W barrel as soon as fitting and recoil spring queries are answered. If anyone has thoughts PLEASE don't be quiet.

This pistol sold today (11/02/2017). Thanks for the interest.

Hi,

Will break out the camera and take a few.

Probably post late tomorrow.

Thanks for asking.

Hi All:

Does anyone know if the Grand Power P-40L 5" .40 S&W barrel will fit, or can be machined to fit, a Grand Power P-40L 10mm? Also, what are the recoil spring weights appropriate to those barrels?

For Sale: Smith & Wesson 1006, 90% (less than 500 rounds fired), 3 magazines, like new tan Galco Miami Classic w/2 magazine carrier. Will entertain offers.

Hi sqlbullet,

Thanks for the information.

I'm considering selling the S&W 1006 (3 magazines & a Galco leather shoulder holster with 2 magazine carrier) and replacing it with a Grand Power P-40L 10mm. While the additional capacity and rotating barrel are appealing, giving up the 1006's strength causes doubts.

Thanks for any advice.

Hi PC Florida,

Sorry for the delay in responding. I've been traveling.

My query relates to the strength of the GP P-40 or P-40L in 10mm. My concern relates to the horror stories which surface about full power 10mm loads causing extreme wear and, in some cases, part failures.

I really feel the GP P-40L-10 is an ideal pistol for the load and am considering selling my 1006 and replacing it with the Grand Power.

Will appreciate any thoughts.

Thanks,

Bernie

Hi sqlbullet,

The early Colt Delta 10mms, according to several reports, experienced structural problems and some cracks when firing full load 10mm cartridges. I have seen no such comments on the 3rd generation S&Ws. The only repeated complaint with 1006's relates to the trigger.

This thread is raised because while I've owned an early 1006 and enjoy that pistol, the rotating barrel action and 14 cartridge magazine capacity of the GP P40 has appeal, particularly in hte long slide (5" barrel) version.

Best regards,

Bernie

Hi Shadow,

As on my general interest post, thanks for the thoughts. Will try the Facebook option you suggest. Tried the Grand Power Forum and Eagle Imports without success. If the barrel dimensions are close (presuming the frame and slide of the P40L are also) the swap should be possible. Glock 20 and 40 10mm magazines accept .40 S&W cartridges. The difference in length (21.59mm vs 25.2mm) is 3.61mm (0.142 inch) may permit such use in GP mags, as well.

Being familiar with Colt 1911 structural problems, 10mm full load stress worries me in firearms originally designed as 9mm platforms. Glocks, while not favorites, appear to handle 10mm loads, as well as anything else for which they're chambered, without distress. Is the GP as strong as a Glock? Will heavier 10mm loads impose unacceptable wear on the GP rotating barrel?

No local (Reno, NV) option to examine the pistol exists and print/video 'Torture' or 'Stress' tests have not been found, finding answers is difficult.

Best regards,

Bernie

Hi Shadow,

Thanks for the thoughts. If Bar-Sto, or someone, was still producing .40 S&W barrels for the 1006 this thread might be academic. Like the 1006 and love the 10mm, but might like the option of shooting the 'small & weak' on occasion. Have been interested in the GP for quite some time. Was looking for a 9mm K100 until acquiring a CZ P10C. Would enjoy hearing any durability issues.
Best regards,
Bernie

Hi All:

Does anyone have experience with the Grand Power P40 or P40L? Particularly one chambered in 10mm.

I am interested in that pistol as the rotating barrel is claimed to absorb recoil. However, I worry about it's ability to withstand repeated use of full power 10mm loads.

My current 10mm is Smith & Wesson 1006 purchased new in the early '90's. My interest is in replacing it with the Grand Power 5" barrel or a Glock 40. The additional magazine capacity, of it and the Grand Power, as well changing cartridge to .40 S&W with a barrel swap has appeal.

Will appreciate any thoughts.

Best regards,

Bernie

Hi All:

Am interested in the new Grand Power P40L 10mm. That pistol is available in 10mm, .40 S&W and .357 SIG calibers. My queries are:

1. Are the exterior barrel dimensions of all those 5" barrels the same, or close enough that a gunsmith can fit them in an existing frame/slide combination?
2. Are the recoil springs the same for all three cartridges?
3. Will the 10mm magazine accommodate .40 S&W, as well as .357 SIG cartridges?
4. My current 10mm is a Smith & Wesson 1006. Will there be a significant difference in felt recoil between that pistol and the Grand Power (rotating barrel)?
5. Does anyone have familiarity with the Grand Power pistol and care to offer an opinion on that pistol's durability with the 10mm full power loads?

Thanks,

Bernie
