thread adapter for Sig Sauer and Glock Gen 3 – M13x1 to other thread

Description

A thread converter for handguns with M13x1 thread

This thread adapter for Sig Sauer and Glock Gen 3 solves an old problem. That of the European pistols dating before the standardization M13.5×1 LH.

They are few in number, but we still meet them today on the shooting ranges. We therefore propose to convert their threads to make them compatible with more silencers.

Since we are talking about handguns, we machine this custom part to cover a threads lenght of 14 mm (.551″), no more. Be careful with this setting if you use it on anything other than a pistol.

Output sizes of this thread adapter for Sig Sauer and Glock Gen 3

By default, we offer this converter to the most common handgun threads today:

• M13.5×1 LH (most common in Europe)
• 1/2×28 TPI (most common in the US)
• M9x0.75 (for Glock 43 suppressors)

Choose your output thread according to the silencer you want to screw on.

How can I be sure that my weapon is in M13x1 ?

The M13x1 is a right hand metric thread. So its full name is actually M13x1 RH. To screw an accessory on, turn clockwise. This is a first clue.

This thread adapter for Sig Sauer and Glock Gen 3 screws onto barrels with an external diameter of 13 mm. Measure yours with a caliper. If you find a measurement between 12.96 mm and 12.70 mm, then you have an M13.

Finally, an M13x1 thread is characterized by a distance of 1 mm between two ridges. So you can place a ruler next to your thread, and count the ridges over a length of 10 mm. If you find 10, you win.
