GP 1945 Bolt-Action Pen PRO — Titanium & Aluminum EDC

GP-1945 Bolt-Action Pen PRO: write, whistle, break glass

Because writing tools shouldn't be boring. The GP-1945 PRO is a tactical writing instrument inspired by the end of World War II, and the EDC ecosystem's writing + emergency tool. Its unibody pen body is machined from 6061 aluminum or Grade 5 titanium (the bolt, tip and clip are separate parts), with a patented bolt-action mechanism, a tungsten-steel emergency glass breaker and a multi-tone survival whistle — because you never know when you'll need to sign a check and escape a locked vehicle.

• Quick measurement — 1-inch and 10 mm notches on the machined grip
• Unibody pen body in 6061 aluminum (Dark/black or Original/silver, knurled, anodized) or Grade 5 titanium (Dark or Original/polished, smooth)
• GP22 refill (Lamy M22 compatible) — an extra refill is included
• Lifetime warranty

PRO or LITE?

Same pen, same template, two tops. Both have the patented bolt action, the multi-tone whistle, the measuring notches, a unibody pen body and an extra GP22 refill. The PRO adds the tungsten-steel glass-breaker tip and comes in aluminum or Grade 5 titanium (135 mm; checked luggage). The LITE has an open flat top, so the whistle is always ready; aluminum only (133 mm; carry-on OK).

Bolt action

A delightful bolt to start and finish your writing: it feels and sounds right.

Multi-tone survival whistle

The integrated whistle can exceed 100 dB. Slide your finger along the air tunnel (the clip) while blowing to change the pitch. On the PRO, the whistle is exposed when the glass breaker tip is unscrewed.

Tungsten glass breaker

The PRO's back-end tungsten tip is a functional emergency glass breaker, independently tested in published videos (Spotter Up, Gizmodo Japan). Aim for a corner of the window, not the center — glass breaks more easily at the edges — and strike firmly with a focused, direct impact. The tip also doubles as a striker for scraping magnesium off the MG-Core.

Everyday carry

GP22 refill

The barrel is shared with the whistle and glass-breaker mechanics, so the GP-1945 uses the GP22 compact cartridge (medium point, about 800–1,000 ft of writing) or a Lamy M22 refill. Standard Parker refills are too long and do not fit. To change it:

1. Retract the nib into the pen body (bolt action retracted).
2. Unscrew the front section of the pen (the tip section below the grip).
3. Remove the spring and the old refill.
4. Place the spring onto the new GP22 refill.
5. Insert the new refill, making sure its top end seats correctly in the bolt-action mechanism.
6. Screw the front section back on.

Aluminum or titanium

6061-T6 aluminum (about 1.4 oz), Dark (black) or Original (silver): the lightest, with a knurled grip and an anodized finish that may scratch after years of hard use. Grade 5 titanium (about 2.0 oz), Dark or Original (polished): warm to the touch and impervious to salt and sweat corrosion. Grade 5 is too tough to knurl cleanly, so the grip is a smooth satin finish that celebrates the titanium.

A pen you can play
