2. Hard To Break In

The DP- 12 is often very stiff and offers excessive resistance when cycling between rounds during the break in period. This is especially common with newly manufactured shotguns and was even a problem with the Kel-Tec KSG as well. Tight tolerances are the primary cause of long break in periods with DP-12s.

The only way to get through break-in periods is to fire more rounds! Shooters should also be sure to clean and lubricate the firearm before its initial use to make things operate smoothly.

Owners can also consult the manufacturer’s recommendations for specific guidance on breaking in their DP-12 shotgun, which may include a recommended round count or other tips for a smoother transition from new to well-functioning firearm.

Very tight tolerances need to be held for the trigger to work properly.

Make sure you trigger is 100% clean and free of debris to fix most trigger issues. If there are still issues contact the manufacturer to get your trigger switched out.
