XDMAN's take on the Springfield Hellcat RDP

[xdman]

At least we now know what the Hex WASP sight is am I right? This is why the RDP gets me all giddy all inside.

Springfield Armory RDP Hellcat — TactiCool

More than just a grip zone upgrade, the Hellcat RDP Rapid Defense Package is not necessarily a version 2 Hellcat. But more like a special configuration that is meant to expand the Hellcat’s carry capability. And yes you can sprinkle in some upgrades for good measure ending up with a kitty that has m

Thanks xdman,
Very nice surprise and great article!
May be almost time for real early Christmas present?

Hmm. Safety model?

You have my attention.

Educate me please. What's the difference between a Compensator and a ported barrel.

Ported barrel is integral; some compensators are add-on/ take off, like 1911 bushing compensaors. I think anyway.

Correct

When can I get my hands on 2 of these?
Alot of new models, no stock anywhere in my area.

I was curious as to whether or not an I would be able to get parts to upgrade my osp version to the RDP. Hoping you could get a threaded barrel and the compensator and just swap them out. Unfortunately I was told this was not possible. I have to say I am pretty disappointed in them not offering these parts.

 

[HansGruber]

Correct

Any chance we can get a pic of the barrel showing how the comp attaches?

I assume there’s just a small locking lug machined in?

Wonder if you’ll be able to add the manual safety to the original Hellcat at some point?

Doesn’t seem like it would be that difficult to do. If SA doesn’t do it, I’m sure someone will come up with an aftermarket barrel/compensator combo to sell.

Yeah, that doesn’t show how the barrel is machined.

 

[uspatriot1960]

Yeah, that doesn’t show how the barrel is machined.

Does this help?

Kinda...looks like a notch or divot is cut at 6:00.

I"m just wondering how difficult the cuts would be to replicate if I wanted to move it to a different pistol, or if the comps would become available aftermarket.

Yeah, looks like a notch to me too. It’s where the retractable alignment pin would go on the compensator.

Looking at that barrel...that appears to have a lot of extra “meat” between the threads and the front of the slide to accommodate the cutout.

Interesting.

Looks like the notch is cut back pretty close to even with the guide rod standoff. The barrel on the regular Hellcat is 3” and the barrel on the RDP is 3.8”. That should give an indication on how far back the threads are cut.

I am going to attempt it with my XDME OSP, threaded barrel. Yes you will have to cut a shallow relief cut at the 6’oclock. Just enough to be able to catch the latching mechanism. You know I am going to have to be the first one in the country to have an XDM-Hellelite.

Compensator looks and sounds to be a thread chaser type with a compression lock on compensator's threads. - Especially with mentioned lever mechanism. Was also thinking of barrel divit for alignment along with high barrel shoulder/limiter above barrel threads. Sounds like good well thought out idea/invention. Eliminates o-ring or compression washer too. Nice stuff!
