Overall Length: 3.052"
Rod Diameter: .25"
Guide Rod Material: Stainless Steel
Reverse Plug Material and Finish: Blued Carbon Steel 
Recoil Spring Type: 22lb Flat Wire Commander Spring .45 ACP and .40 S&W [ISMI Spring]

This kit reduces recoil and increases longevity of the spring system in Springfield 4" guns.

If you have a 9mm S&W you will need the kit with the 14lb flat wire spring available here.

The kit includes a 1/4" guide rod, reverse plug and ISMI flat recoil spring. 

All systems use a 1/4" guide rod made from solid barstock with a take down hole. 

Reverse plugs are Blued carbon steel.

Meant for use in Springfield 4" .45 ACP & .40 S&W 1911's only. This will work on the Range Officer Compact and Springfield Champion.

Some older model Springfields used a different style reverse plug. Our kit does not work with these older models.

This kit fits:
EMP 4" Lightweight Champion .40 S&W
EMP 4" Concealed Carry Contour .40 S&W
Champion Operator Lightweight .45 ACP
Range Officer Compact .45 ACP
Range Officer Champion .45 ACP
Range Officer Elite Compact .45 ACP
Range Officer Elite Champion .45 ACP

All kits are drop-in.

The Champ Finally Earned its Name
I have a "new to me" Springfield Loaded Champ. Loved everything about the pistol except that it would not feed defensive jhps no matter what. Frustrating! The original plan was to use it in my personal carry rotation. Tried a lot of ammo "fixes" but none made much difference. I heard about this drop in, read the reviews and decided to order it. I am so happy that I did. It is a true drop in part- less than 2 minutes. Seemed to dry cycle just fine. At last I took the "chump" to the range today hoping to notice some positive change. I was blown away at the huge difference this guide rod made in my firearm! Even the jhps cycle properly now! I was all smiles after the range. The pistol felt better on recoil and was altogether amazing in performance. It went through every jhp I had with me and was ready for more. THIS is an amazing corrective addition for any ammo picky Springer 4" 1911. I am now proud to state that I finally have the "CHAMP" I originally wanted! Thank you EGW. Great product and rapid service. I will happily recommend this guide rod assembly to anyone who has a balky 4" 1911. What a difference it made for me!

Best thing you can do for you Champion Operator.

THEE best kit out there
I recently purchased a LW Champion Operator with the stupid dual spring guide rod system. Now the system itself isn't so bad but the guide rod screws in to the base plate and therefor unscrews when you fire it! I didn't mess with locktite and super glued the thing in place but sometime during my day at the range the rod work itself loose and disappeared and I didn't notice until I got home and took it down for cleaning. The gun still fired flawlessly!

Anyway, I contacted EGW about this kit that was out of stock and they promptly replied, and as soon as they were back in stock I got an email from a human being letting me know! What a concept! The kit came in this morning and I have so far fired 150 rounds of ball ammo and about 20 rounds of 230+p ammo, and I've got to say the felt recoil is much less, and reliability is at 100%, even with lower grade ball ammo. I figure if it will shoot crap dirty ammo then it's good to go with about anything else.

I am more than happy with this kit, and it comes exactly how you see it, paper clip and all, for a easy 1 minute install. It's the most drop in kit you'll find for these SA 4" guns. If you own a 4" Springfield, buy this kit. Don't wait until your guide rod disappears.

Also, take down is much easier with this kit.

Wish This Came With My Gun to Begin With
This kit is perfect. My stock two-piece guide rod on my Springfield LW Champion Operator broke at the base plate and shot out onto the range. The gun still fired and I didn't notice until I got home. I didn't want to mess with the two-piece setup anymore so I opted for one of these. This actually wasn't available when I ordered and I had ordered the other 4" guide rod kit that EGW sells and once I placed my order, I called to make sure it would work. Jim, the fantastic customer service rep at EGW, returned my call and let me know that the one I ordered did not fit my gun but that as soon as the correct one became available he would switch it out and get me taken care of. A few days later it had arrived. I dropped it in and it has worked flawlessly. So much better having a stainless steel guide rod vs that crappy piece of plastic that it came with. Highly recommend to anyone with a 4 inch Springfield.
