Barrel conversion for smith and wesson compact from 40 s&w to 9mm - Stormlake Pistol Barrel for 34142 Smith & Wesson M&P Compact 9mm Conv For 40SW/357Sig 3.6" SS

Excellent quality and fast shipping on this item from Optics Planet. Very Pleased with the item and Optics Planet all around. Drops into place without a hitch and performs as it should. Would recommend without hesitation. Using a coupon code I found I could buy this item cheaper than any other dealer was currently selling the item for and was able to receive it faster than through other methods. I ordered this conversion and the 357SIG barrel conversion and can NOW interchange within 5 minutes from 40S&W to 9mm to 357SIG and back again. The only negative is the fact you must purchase new magazines to use this conversion, whereas you can use the 40S&W magazines with the 357SIG, without having to buy more magazines. A strong positive is the fact Smith and Wesson makes replacement slides/uppers to replace on your firearm to show the gun is entirely marked as 9mm while using it with the conversion, instead of having a 40S&W slide with a 9mm barrel installed in it. StormLake makes an excellent product that is superior to other conversion kits and is more reliable than trying to use a factory barrel instead of the conversion, as you should for safety.
