The 10mm cartridge is an excellent hunting cartridge, on par with a 44 Magnum. Quite stout recoil in a semi-auto pistol. For most, a bit too much for a defense pistol but perfectly acceptable for medium size game. Perhaps the most serious issue has nothing to do with the cartridge but the pistols that fire them. From the beginning the Bren Ten, SW 1000-series and Colt Delta Elite had durability issues. The first proper pistol to handle this punishing cartridge was the Glock 20. 

Sig released the newest 10mm on the market, perhaps one of the strongest 10mm pistols available. The P220 was designed with the 10mm in mind. Not only is the slide stainless steel but also the frame. The strengthening of the frame, along with a heavy recoil spring, make this pistol more tame than even the Glock 20. The pistol is available in both double/single action, as well as single action only.
The Galil Ace first entered the United States chambered in 7.62x39mm. It accepted AK-type magazines and was offered in both Carbine and pistol model. This is my favorite variation! Next to appear is the 7.62x51mm (.308 Win). Earle designs used the original 7.62x51mm proprietary Galil magazines. The ones imported took the SR25/AR10 magazines. But the one truly anticipated was the 5.56x45mm (.223 R.E.M.) version. This has been the most successful version of the ACE series recently adopted by the Chilean Army as well as Colombian Army. Also worth adding is that the 7.62x39mm version was adopted by the Vietnamese Army.

The 5.56mm version uses the standard STANAG (M16/M4) magazine. Earlier versions used the original Galil magazine. Another new feature is the bolt catch and release. This feature will eventually move over to the 7.62x51mm rifles/pistols. The 5.56mm is offered in a pistol as well.

For as highly modular and versatile that the XCR is, I am shocked it has been given so little media attention. Designed for the SCAR program around the 2006 time period, the XCR has gone through many incremental changes to keep evolving and improving the system. Looking at the XCR, the first thing to understand is that it is NOT an AR15!

In fact, if I recall, the only compatible part is the pistol grip. It is a long stroke piston and uses a removable barrel. By rotating a screw, you can remove the barrel and swap with various calibers and various barrel lengths. This one was shot in 5.56mm, 300 Blackout and 7.62x39mm.

Changing out barrels and bolts is easy, the tricky part is the adjustable gas system. You balance for one round and change, you may have too little or too much gas causing failures to feed. You have to understand ammunition creates different chamber and port pressures. I have to say I enjoyed firing the 7.62x39mm round the most. The C Product Defense fed flawlessly. This is an excellent and viable weapon system.
There has been heavy anticipation as to what the newest Generation of Glock pistols was to be. Many bloggers have shown pictures of the G17 Gen 4 with front slide serrations to be that, which obviously was wrong. The Gen 5 comes out of the G17M program which was an FBI program. The new Gen 5 includes some significant enhancements, such as: The trigger mechanism has been redesigned and is not backwards compatible with previous generations. The slide stop is now ambidextrous. The barrel has also been changed and is also not backward compatible.

Traditional Glock barrels have been cold hammer forged shallow rifled polygonal or octagonal rifled. Due to this configuration, the barrels were not safe to fire lead ammunition. The lead fouling could cause catastrophic failures. The barrels are designed for jacketed ammo and the barrels last basically forever, which in my opinion is a major accomplishment. The Gen 5 uses the same type rifling but in a hexagonal rifling pattern. This is a standard pattern, but some say this makes the Gen 5 lead safe. It is NOT!

The shallow lands and grooves are manufactured the same way, and rifling pattern (polygonal, octagonal, hexagonal) makes no difference. The new Gen 5 Marksmanship Barrel has the hexagonal rifling with the rifling moved further rearward into the chamber area reducing bullet jump into the rifling. The muzzle is crowned as well.
