Change DB9 magazine followers with a stronger plastic. Yours get chewed up very quickly using ammo that does not harm all my other brand firearms.KIMG0189.JPG

DB9 / Re: Magazine "followers" getting chewed up from minor use.
« Last post by Big Daddy on May 24, 2018, 10:56:23 PM »
I was able to fairly easily pull the follower off by hand on the magazine in question. Took a hammer (Jet Mechanic; USAF trained)and tapped the mag lips a little closer. (no caliper). Loaded mag and racked slide repeatedly. No feed problems. Its funny that my S&W, Kahr, Glock, Berretta, and Sig magazine followers don't suffer from same wear as my DB9. Same ammo. I think Diamondback needs to change supplier of their followers with something a little less soft in material. Thanks for your tips. If not for this forum, I would have traded it in toward something else.

Hmmm, that doesn't explain the follower popping out. If you have calipers, measure the lip opening, both front and back and let's see if it's in line. When the last round is extracted it shouldn't crash into the face of the follower like yours shows. The round should hit the curved portion, pushing the follower back down a bit as the case is ejected. I do, however agree that cases with sharp edges can exacerbate a problem. Good luck!

DB9 / Here is the ammo that I used.

I felt a round from each of these. Hornady CD and Sig Sauer V-crown were both pretty smooth. The others were much sharper edged. I will stick with the
Hornady and Sig Sauer.

DB9 / Response from Becky at Diamondback

Here is response after sending in photos of magazine followers getting chewed up after 50 rounds.

"This is normal wear on our magazines. It should not affect the functionality of the firearm, but it could be caused by different kinds of ammo. Some ammo has sharper edges that could catch and scuff the plastic."

I will inspect the ammo and use the least sharp edged shell casing. It did not seem to affect function of firearm, so I guess I won't worry.

Gunsmithing / Bore Deburring
« Last post by mcr1010 on May 23, 2018, 12:46:58 PM »
I did not see this tip for removing very small burrs not visible to the naked eye, from the edges of lands in the bore, so thought I would pass it along. 
For the 9mm you will need a 5/16 dia. wood dowel about 8-12 inches long and SS wire scouring pad.   Cut a few coils off the pad and wrap on the dowel.  Push or drive the dowel thru the bore in both directions.  The  SS coils are not hard enough to wear the bore lands, but will take off the burrs and keep the bore from fouling as quickly.  Also, this method is good for cleaning out heavy fouling. 
This tip was on the Kel Tec forum years ago by an old time gunsmith......Jack  RIP Jack.

The followers look to be extended out a bit too much. This thread discusses dimensions.

You could also try rotating the spring to place more pressure on the rear of the follower, but a follower getting ejected is a pretty good sign that the magazine lip dimensions are off.

Here are mine.
