Failure to feed, chapter 2
« on: March 09, 2018, 05:15:05 PM »
I just received My RAMI from the warranty service.  They definitely made some changes.  Their enclosed letter said the following:  "Extended throat, adjusted feed ramp, extractor, slide stop, breech face lead-in.  Test fire good with Magtech JHP a47 gr."  My original complaint was occasional failure to fee with Federal 124 gr. HST.  (The center of the hollow point bullet slammed into the bottom edge of the feed ramp.  This only occurred about 1 in 20 shots.)

They definitely worked on the throat and feedramp.  I did not check the slide stop, and don't know what they may have done to the extractor.

It arrived too late to take it to the range today.  As soon as I get the chance, I will shoot it and let you know.  I am hoping they have a standard modification that will improve the reliability of these little guns.  I will let you know.

Nice. Interested to hear how it does. Best of luck.

I just joined the forum today after buying a RAMI BD. Although the RAMI is very accurate it almost always has multiple failure to feeds from both the 10 and 14 round magazines. I swapped out the 14 round mag spring with a +5 Wolf, same deal, FTF. Yesterday at the range was extremely annoying as out of 300 rounds total, I had 34 FTFs, 5 FTEs from both magazines.
I'll be contacting CZ next week to investigate this issue.

That sucks. Sorry to hear. Was your gun brand new? I wonder if they had a bad run recently. Mine is a 2017, with the black coating on the barrel... and other than one FTF in the first magazine I ever fired through it... it's been flawless. With both the 10 and the 14.

Good to hear a report of exactly WHAT CZUSA did to the gun to fix it.

I had a few problems with my 2015 RAMI BD that improved when I polished the feed ramp and throat.  My 2017 RAMI BD came from the factory with ramp and throat polished already, and it's been OK.

I'm always looking for decent JHP's that are priced reasonably enough for practice AND Defense.
I tried some Federal Independence JHP that shot very accurately but had very aggressive cuts on the tip. Occasionally hung on feed ramp of RAMI and a few other guns, but NEVER on my P-07's.

I recently found a great deal on S&B 115 JHP  SB9C's from SGAmmo.  The tip is less sharp-edged and they run 100% flawlessly in all my guns. At 23 cents shipped they're cheap enough for range ammo too. 

S&B is a Czech company and I notice most of my test targets from CZ use S&B ammo.  I've really liked their 124gr SB9B in my CZ's.  YMMV

I bought the gun new.  Yesterday, the 4th round ftf using Winchester fmj and 14 round mag.  Fired another 80 or so rounds, of varying types and brands with no more ftf.  The warranty service had reshaped the feed ramp.  I polished it before firing.  If this RAMI cannot be made to work reliably, can you recommend a different subcompact 9mm that is stone-axe reliable, or to I need to return to my air weight .38 chief special revolver?  I retired this gun because it is very difficult to shoot accurately and kicks like a mule.

Bummer.

If your fav SD round is HST 124gr.  Then I recommend shooting a couple boxes of 124gr FMJ or even 147 gr. perhaps observing the feed ramp to see if/where the bullet nose is bouncing off the feed ramp.  A dirty feed ramp will show a clean or copper flake at the problem area if ramp related.  Take a picture for CZ USA.  If no failures, clean, lightly oil and start burning through SD ammo until you gain confidence.   Hate to say it but any model can have a lemon.  CZ USA made my Rami right and my SD round is more challenging at 147 gr HST.  I now carry it with confidence, but it took 5-600 rounds to get there.  Frustrating, yes.  But I'm happy I didn't abandon it.

For pocket carry, I use a Bereeta Nano with great success from day one.  The internet abound with how crappy THAT gun is.  It shoots much like a DAO revolver, long hard trigger pull, so be aware of that.

Have you replaced the outer recoil spring (should be replaced every 500 rounds or so)? Actually, it's a good idea to keep a fresh spring in for SD / EDC and put the milage on other springs during practice.

Can you isolate the ftf problem to any particular magazine?

115 gr rounds should feed better than heavier projectiles and 115gr. +P actually dumps more energy into the target anyway.

There's a plethora of sub-compact strikers, but finding a reliable lighter weight hammer-fired DA/SA Sub-Compact is like finding a needle in a haystack. Especially, high capacity like 10+  The RAMI is among the few, and it should be a solvable problem. The fact that you had it choke on a standard FMJ shortly after return from CZ isn't right; and I would demand that CZ figure it out. If it wasn't quite going into battery, that would indicate a throat or recoil spring issue.  But jamming on feed ramp; my guess is it's probably a combination of things out of spec, magazine, recoil spring, and/or timing. JMO. There are such things a lemons, so If CZ can't get it right; maybe they should just replace the gun or refund your $$.

I've had a few guns that no matter what I try; I just can't get to work for me. If they're for SD, eventually you have to cut and run. Someone else can figure it out.

I'm waiting to see the long-term reports on the Springfield XD-E. But it could take a few years to really shake the bugs out of any new model.

Oh... not all metal, but the Rami infringed on my Beretta PX4sc, a phenomenal gun, pehaps a wee bit thicker with 3" barrel, 13 round mags that also shoots like a full size gun.  If you don't like the safety decocker, a simple spring removal makes it decocker only.  This does not feature the rotary barrel action of the rest of the PX4 series that seems to be the rage from beretta fans.  If you buy into the rotary thing their "compact" is only a wee bit bigger than the sub compact.  I also trust my life with with this weapon.  The full size 17 round mags work as well.  I bought some rubber sleaves for the full size mags for a flush full grip for target shooting, but at least for me not really needed.  Cool pinky extension flip down mag base option for a full grip as well.

Good suggestion on removing the redundant safety on the PX4sc. DA is plenty of safety IMO.
Berettas are generally superb (I had an 8000 cougar compact that never failed) but I just couldn't stomach that slide mounted decocker plus safety. I feared in a pressure situation I would pull the trigger and nothing would happen. Opps, safety was thumbed down like my 1911's but safety's still on. Ugh!

Tyrone:  Tell me about your Beretta.  Chudson_2000@yahoo.com  I have a 92 compact.  1200 rounds with no malfunctions of any kind.  Too big to carry.
