Have any of you considered converting a 9mm M&P to 356 TSW? Shouldn't be much different than the 4013/4010 conversion. Us a 9mm finish chamber reamer to deepen the chamber from 19 mm to 21.5 mm and change the recoil spring.

An update on the 356 TSW Glock 17 & Glock 19 Briley barrel conversion kits, Corbon 115 grain JHP and Underwood 115 grain JHP: during testing in June 2020 Corbon averaged about 1612 fps from the Glock 17 conversion kit and about 1569 fps from the Glock 19 conversion kit. Underwood averaged about 1570 fps from the Glock 17 conversion kit and about 1540 fps from the Glock 19 conversion kit. Accuracy and feeding were good, no anomalies were observed. Starline makes strong brass, Corbon and Underwood load great ammo, ISMI springs and LWD guide rods are first rate, and the Briley barrels are top notch. Glocks are....Glocks, and with 356 TSW they are that much better.

Ammo is available through Ammoseek, Corbon, Underwood, Selway, Midway.

356 TSW Glock conversion kits are available on Gunbroker.

Look for others to catch up at some point with even more options (Apex/Hornady)?

Lots of cool parts available for cheap.
Has optic, comp and light.
9mm +P+ right now but trying to get a 356 barrel together.

I have been shooting a 356TSW M&P for 3 or 4 years now

Apex Tactical has been talking about having 356TSW barrels for the M&P line of 9MM pistols ready to go

I just checked the website and do not see any, I will contact the Company but they are probably getting ready to travel to the SHOT Show
