"Flattened primers" w/ rcbs hand primer & 9mm

First ever venture into pistol handloading and noticed something after loading a small batch of 12 cartridges last night. (Want to get those out to the range w/ my Springfield XDM 9 and see how they load/fire/cycle/etc. before loading a bunch...)
I'm priming w/ the rcbs hand primer that came in my rc supreme kit. (It's so easy to use and primes my 6mm rem rifle cases perfectly.) However, I noticed that all of my pistol primers last night looked flattened, or smeared, for lack of a better description.
Does it still take a bit of "feel" to get the small pistol primers right w/ the hand primer & avoid flattening them? I may take another swing at it tonight and see if a little less pressure at the end of the squeeze helps avoid this. Anyone have a thought about it?... T
he primers are Remington 1&1/2. (Are they known to be any softer than other brands?...) The batch of cases I was using last night were all Win.
Also considered, after the fact, that I could take the small primer rod out of the device and put the larger one back in. (the one I use for rifle cartridges) This would only let the rod go as far as the base of the cartridge, seating the primer flush w/ the base. Might that leave the primer not-quite-fully-seated though?
Thanks in advance for any input.

Waywatcher - yeah, the off-center crescent shaped marks showed up on a few of mine last night. The reviews of that bench primer sound glowing.

Sidewinder - I might be. I think using a softer squeeze (i.e., not quite gripping down to the last little bit of give...) is probably what I'll try first to see if this problem goes away.

OCD - No, mine is not the universal one from your link, it's the other rcbs tool in this link:

Still might also try putting the large primer rod in, too, and see if that helps keep me from "over-squeezing"...

Thanks,

You're both right...

(sorry to be so late in getting back w/ more info... my daughter's h.s. b-ball scrimmage had me tied up for most of the evening...)
The marks on my primer were of the type Waywatcher was imagining - where the mark is the same size & shape of the primer rod - where most of the primer was flattened and the crescent shape was the "unflattened crescent on one side.
RCmodel, what you guessed might be Waywtchr's issue is actually mine - small rod w/ the big black insert. Remember the part about being new to this What a "duh" moment - totally forgot to switch that out.
There is definitely too much wobble w/ the black plastic (large) insert with the small rod.
Here's an odd customer-service related plot twist, though... When I went to assemble the two halves of my smaller white plastic insert, I realized that I have two "left" or "right" halves - not one of each. A little packing error I guess. So, I will in fact be giving RCBS a call about that tomorrow.

When I couldn't try the white insert w/ small rod tonight because of that, I put the black insert back on and used the proper large rod with it. No play or slop at all there. As suspected, since that rod is too large to go "into" the primer pocket of the 9mm, it stops flush w/ the case, leaving the primer where it should be and without any apparent damage/marks.

Great site here. Great folks always willing to help. Thanks for getting me thinking and realizing what the problem was.

RC- thanks again for your input about the primer depth. You know, even just after I typed that in my last reply, I had a fleeting thought that maybe I had read something somewhere about someone's primers not being seated all the way... Really appreciate the help.
I'll lightly "re-touch" - this time w/ the small rod - the 5 I did last night.
I did give RCBS a ring this morning - my first call ever to them and, as advertised by others, they were excellent. Sending out two left halves of the small insert to go /w my two rights... They also were helpful on a couple of other general questions.
