Video Review of Sig P220 10mm

REDLINE · December 13 2015 12:06:50 AM MST

Regardless that I personally don't have a want for one, it is a very nice firearm in it's own right. Hickock45's video was great as usual. I was left with 3 questions in mind after the video, one of which I was able to find the answer on at SIG's website which was a barrel length of 5.0". The other 2 questions I'm left without answers to are;

What is the recoil spring weight?

and

How good or bad is the 6 o'clock chamber support? Is it more like a Kimber 10mm Auto barrel which is super awesome, is it more like a Colt DE barrel which is super horrible, or is it in between like the Glock barrels in 10mm Auto?

One thing Hickock45 repeatedly mentioned was the heavier SLIDE weight of the P220 over the G20 and in general, and mostly relating to less felt recoil. Obviously a lot of the weight of the P220 over the G20 would be frame related and I wonder if that's more what he meant at least some of the time. Or is it that there is a notable between the actual SLIDE weights of the P220 and G20. I don't know.

I can't imagine the slide weighs that much more than a G20. The G20 weight is mostly slide, 22.3oz out of 30.6 oz is slide, barrel and RSA.

That means the Glock 20 frame+magazine is only 27% of the weight of the gun. Like the to Witness (57%) and my 1911 wide body(53%), I gotta think the Sig would carry most of it's additional weight in the frame.

No. Sneed Hearn was one of WC Fields's fictitious names.

I have the 220 Elite (two tone).

Took pictures, but the images were too big ${$default_smiley_smiley}$

The entire cartridge is supported by the chamber.

The slide weight without barrel and spring is:
14.85 oz

sqlbullet · December 13 2015 07:15:58 PM MST

14.85 slide along is well under the G20, and even under the G29:

cgreth, could you also post the following weights?
Complete pistol with a magazine
slide assembly
barrel

That would allow me to complete the spec info on the above thread for this gun.

That is awesome, and a first outside of a T/C Contender! Sure would like to see a pic or two.

I sent a PM offering to host the pictures. Sounds interesting!

cgreth · December 14 2015 03:44:42 PM MST

Complete weight of pistol and empty factory magazine - 2 lbs and 12.25 oz

Slide with barrel and spring - 1 lb and 4.70 oz

Barrel only - 4.30 oz

Under zoom which i did for the pictures, there is a very thin portion of the cartridge that is unsupported by the feed ramp. Still looks too small to be an issue with case bulges, smileys or blow outs.

That is really good case head support

One thing I haven't noticed is the barrel rate of twist...
Does anyone know the rate of twist ?

sqlbullet · December 15 2015 08:01:50 AM MST

One of the owners here would have to be bribed to measure the twist, cause it isn't posted with the specs on their website.

Usually isn't a huge concern on stubby little handgun bullets. For a 200 grain 10mm 1:29 is adequate to stabilize.

That's a good question, but it's not listed or discussed with any conclusions by them. Typically, it should be 1:15 or 16, like the majority of the other common pistol calibers. None of the available .40 caliber bullets require faster than about 1:24 with the greatest SD. Faster is not, necessarily, better, as it typically increases peak pressures and decreases velocity. It can also affect bullet construction integrity, if too fast. As SQL said, 200 gr. bullets in this caliber, and any that may be used, are well within the scale of practical.

Well if someone measures it, let us know...specs could be updated. I am aware of common specs for twist, just wondering what they picked.

That's not entire cartridge support but it is clearly better support than my stock Glock barrels. The Storm Lake barrel for my G20 looks like about the same support at 6 o'clock but is better around the sides. Kimber still has all our aforementioned barrels beat.

Here's a pic of my Storm Lake barrel support (6.02" barrel for my G20);

Though it's not a 10mm barrel, The_Shadow has a Bar-Sto 40S&W barrel for his S&W 1006 with awesome chamber support that he's posted pics of in the past.

It's a great gun... I wouldn't buy one until they offer an equal to my others... high capacity ${$default_cool_smiley}$

I totally agree! If I am going to carry a large pistol, then it isn't going to be something without at least 13 rounds in a magazine. I don't see the point. If I am going to carry something with lower capacity, it is going to be something tiny like my Glock 42.

However, I am happy to see more manufacturers building great 10mm's even if it is something that I won't be buying. We need more 10's on the market, particularly ones from great companies like Sig.
