Thanks all, I will give a range report hopefully as soon as Sunday if I can get time to get out there on Saturday.  I think I'm probably going to put the stock guide rod and spring back in and buy a box of Winchester Silver Tips or something like that just to be sure it runs smoothly.  Then maybe a round or two of Underwood before putting in the stainless guide rod and 20# spring (I ordered a 22# but they sent me 20#, I figure maybe it's better if I can shoot both the FBI lite and Underwood without changing springs).  As for the grips I figured I'd give em a try since I love the rubber ones from Talon on my XDs .45.  If it's too abrasive I'll sand em down with some 120 grit sandpaper (what Talon says to do) or just take them off and get the rubber ones or just keep it stock.  Either way, I'll keep you all posted.  Thanks again for the welcome!

Here's one

Disregard the pics I'm sorry.  They're all too large.  I'll resize when I have time. 

So I FINALLY picked up a Glock 20 gen 3 (standard, non SF), at least from what I can tell.  Anyway I've fallen completely in love with this gun.  Bought it used stock from a reputable guy (seems like one at least everyone at 2 LGS' know him well enough to let him behind the counter but anyway.  It (was all) stock.  I put abrasive Talon grips on and a 20# Captive RSA.  haven't fired it but figured it would be a good idea since I ordered 100 rds of Underwood.  This is my first glock and first 10mm.  Seller said to call him before anyone else if I ever decided to sell it.  Some holster wear but other than that looks pristine.  Should I keep it stock and fire some big name 10mm lite rds first? Or keep my new RSA in and shoot the Underwood's?  Or shoot them stock?  Also is there any different cleaning and lubing protocol with a glock?  Anyway I love it without ever shooting it and I'll pic dump.  Thanks all.

XDs .45 loaded with glorious beautiful 230 grain HST's.  I carry 7+1 almost all the time since its just about as concealable as the stock 5 rds mag.

VERY light clothing: XDs .45 same as above 5+1

VERY heavy clothing or woods: G20 standard gen 3 w/ underwood 165 gdhp's or BB 220 hard cast innawoods


Pic is old.  XDs now has Talon Rubber Grips on it (which help control ALOT) and on the mag extentions and my EDC knife is now the SOG Escape.  Broke the tip of the Kershaw Leek.

The Speer Gold Dots are another good choice, if there were some HST offerings (projectiles not offered as components other than from pulled 40S&W) would also make a great SD round from 10mm.

But hey if the perp is not wearing a vest, they aren't bullet proof!  There are cast HP bullets that would actually work well.

HST's!!! Best SD bullet available imo.  I carry 7+1 230 grain HST's in my CCW (XDs .45).  I was so disappointed when I found they weren't offered in any 10mm cartridges.  So you're saying they won't even sell .40 HST projectiles?  You actually have to buy a box of 40S&W HST's, literally pull the bullet out ofthe brass, then load it into a 10mm casing with whatever hand load you choose?  Is that even possible to reload a projectile that's been crimped already?  I know nothing about reloading but I'm gonna (try to) start soon and buy reloading for dummies or the equivalent ofthat book 

BTW the cast rounds shouldn't be fired from a stock glock barrel correct?  Because of the weird rifling I think?  So I'd have to grab a lone Wolf barrel for cast bullets.  I was probably going to get a 6" barrel anyhow .

The DT 9x25's were based on 6" test.  The shorter barrels don't yield the upper velocity fosr the 9x25's, commercial loadings are expensive for the most part.
The TC is usually shallow with bullets of this style, the projectiles like the 90 grain 0.355" dia. were made for performance from pistols like the 380ACP's.  Therefore I would think these in JHP would likely have total expansion on or slightly after impact.

Also these shorter lighter 0.355' projectiles seem to have poorer accuracy at distance.

There are some who have pushed the 135 gr 0.400" projectiles to 1700-1800 fps from the 10mm platforms with 4.75"-5" barrels.  This is pushing the envelope of the brass based on chamber case support and actually some have blown out the primers.

Ahh I knew there had to be a catch.  Oh well, I appreciate the info.  Trying to get my hands on some Underwood Gold Dot 155 or 165gr BJHP's as these seem to be the best choices for 10mm SD ammo.  Also need to get some 200/220 TMJ's or XTP's for inawoods activities.

I posted a link near the top of this page which points to a lot of information on this very subject from folks whose job it is to analyze and predict projectile wounding. The "magic number" referred to by the FTU's paper, Dr. Roberts, and other experts is 2,000 fps. As mentioned, there are a lot of factors involved but typical handgun bullets, including the 10mm do not reach the threshold required to make TSC a significant wounding mechanism.

Sorry to bump an old thread but I just got my first 10mm (Glock 20 gen 3) and just joined the forums after this thread caught my eye since I just ordered some Underwood 135 gr JHP's.  So I understand they don't have the velocity to make the temporary cavity significant since they don't reach 2000fps (1580 avg chrono I've read).  Let me ask you guys this... my Glock 20 can fire 9x25 Dillon with just a conversion barrel.  Double Tap makes a 90 grain 9x25 Dillon that advertises 2100fps out of the muzzle.  Assuming it does that, Since that's higher than "the magic number" would that round make the TC significant?  Or are there other factors at work? Yes i know its not a 10mm but it is fired from a 10mm platform and its a 10mm casing  Thanks.
