The PWS BDE 9mm titanium suppressor is the pistol-caliber member of the Primary Weapons Systems BDE line, a modular can you can set up long or short (PWS part no. BDE9). Its core baffles are 3D-printed from Grade 5 6Al-4V titanium, and the removable aluminum baffles that ship with it let you tune length and sound reduction. A universal 1.125-28 thread pattern fits most pistol suppressor mounts, and the baffles are engineered for low back pressure to cut gas blowback. PWS coats the entrance chamber and main body in DLC and hard anodizes the modular baffles. It suits a 9mm pistol or carbine owner who wants one adjustable can rather than a fixed-length one.

Key Specifications

• The caliber is 9mm, for pistols and pistol-caliber carbines.
• Core baffles are 3D-printed Grade 5 6Al-4V titanium, which PWS says is lighter and stronger than machined titanium.
• The modular baffles are removable aluminum, so length and noise reduction can be set to preference.
• The thread pattern is a universal 1.125-28, compatible with most suppressor mounts.
• The entrance chamber and main body carry a DLC coating, a durable finish against wear and the elements.
• The modular baffles are Mil-A-8625 Type III Class 2 hard coat anodized.
• The baffles are taper-threaded, which prevents carbon locking and loosening between them.
• The design targets low back pressure, reducing gas blowback for smoother shooting.
• Symmetrical internal baffle notches are there to help accuracy.
• Exterior texturing helps dissipate heat mirage over a long string.

Frequently Asked Questions
