Just noticed a very small detail that was added to the M&P that you don’t typically see in a pistol and definitely not in a polymer one. They’ve added a slight crown to the barrel which is widely known to improve accuracy. Here’s a description of what a barrel crown is and it’s purpose :
The primary purpose of a firearm muzzle crown is to provide propellant gases a resistance free path away from all parts of the projectile as it exits the bore of the barrel. The secondary purpose is to protect the bore from damage caused by misuse. The third purpose is for good looks which is always achieved when the primary purpose is satisfied.
Good Job Smith and Wesson! I’m liking this gun more and more.
After seeing many people on the XDtalk forums polishing their XD barrels, I decided to try my hands on it too. Thanks fo rogerxd45 and his excellent polishing guide.
here are the tools :
I’m using the Liquid Metal Polish Green Medium Grade from http://brilexsolutions.com
Here’s a close up of the barrel before polishing :
I realized that using the dremel polishing tip took a long long time. After my battery powered screwdriver unit ran out of battery, I switched to using my hands, and it was much faster :
I could cover more surface, much more evenly and much quicker. The tip of the barrel was the easiest one to do. First coat it with green stuff :
then rub away on a flat surface :
It took over two hours to get the chamber and barrel front half polished to my satisfaction. I’m sure I can do more and complete the whole thing, but most of the barrel will be hidden from sight anyway. so here it is completed :
Back on the slide :
Slide locked back :
and the tip :
I ordered a silver guide rod which should arrive from Pistolgear soon.
