20 Gauge Mossberg 185k: Using Slugs - Safety & Compatibility
No, you cannot use slugs in your 20 gauge Mossberg & Sons model 185k. The 185k is designed for 20 gauge shotshells only, and using slugs in it could cause damage to the firearm or injury to the shooter. Slugs are much heavier and longer than shotshells, and they generate a much higher pressure when fired. The 185k is not designed to withstand the pressure generated by slugs, and could burst or otherwise fail if slugs are used in it.
