db-9/db-380
1)You will have to file light and fit tight.
2) Put tiny drop of "gel" super glue w/a tooth pick for a more permanent fit. Has bumps on lower part to hold it in, once in it looks great.
3)Small rat tail file and finger-nail files work.
4)The oriental nail ladies can paint flags,emblems,logos on your plug.
5)Two grip plugs for 14$.
6) fits db-380 & DB-9
other opinions:
1) use militec grease on your rails for 500 rnds.
2) use militec-1 oil with hair dryer, militec tiny bottle & tube of grease on ebay to your door for under 10$each, and last for years.
3) get with eric @ Gallowayprecision.com for new trigger springs (aftermarket & quality). Chris, the owner of the forum designed the springs .
4) de-burr & wax your magazine follower many times while watching tv.
5) spend the money @ mic holster for the kydex trigger cover (google it).
6) l can show u how to make figure 8 shoulder holster if ya want, u will need mic holster for safety no matter what.
