This is a factory Walther P99 threaded barrel with thread protector. This barrel has the LEFT-handed thread pitch of 13.5x1LH. I believe it will also fit the PPQ M1 model but not the M2. Asking $150 and can ship if needed once payment is received. I accept PayPal and Venmo. Contact me here on FGT or text me at two3 nine, 2 four8-93 eight 8.
