thock Posted December 31, 2022 Share Posted December 31, 2022 HAPPY NEW YEAR! We have received the K-/L-frame/.22 hammers back from our engraver and will be shipping them out the first week of 2023! Thank you all for your patience! Link to comment Share on other sites More sharing options...

AzShooter Posted January 1, 2023 Share Posted January 1, 2023 My 4 inch 617 is all anxious for this upgrade. I can't wait to shoot it and compare it to my 617 with the Apex Tactical hammer setup. I'm sure it will be an enjoyable exercise and I intend to write up my reactions to both. Link to comment Share on other sites More sharing options...
Toolguy Posted January 1, 2023 Author Share Posted January 1, 2023 We'll be interested to see what a pro like yourself has to say. For best results, use a stock S&W mainspring and find the lightest rebound spring that works well. While we're at it, Happy New Year! Link to comment Share on other sites More sharing options...

Toolguy Posted January 6, 2023 Author Share Posted January 6, 2023 We have N frame hammers now. We ran out of some of the other parts for the kits, but those will be refilled shortly. Link to comment Share on other sites More sharing options...
thock Posted January 8, 2023 Share Posted January 8, 2023 Yesterday, we shipped the first half of the existing K-/L-frame hammer orders. We discovered that we were low on some parts, but we should have those by the end of next week. We're hoping to ship the rest of the orders then.

AzShooter Posted January 12, 2023 Share Posted January 12, 2023 I received my RevUpHammer kit on Monday and was able to install it in a matter of minutes. It's that easy to do. I put it in my new 4 inch 617. This gun is basically stock. My DA pull iwas set 9 pounds 7 ounces to get 100 % reliability with my favorite .22 ammo and requires 52 ounces of hammer fall to set off my ammo. With an 11 pound rebound spring I have had no problems with the trigger resetting with stock parts. With the RevUp kit I had to put the 12 pound rebound spring in. I was getting too many failures to reset at 11 pounds. Measuring the SA pull it's just over 4 pounds on average with the 12 pound spring. I found that I can get away with 46 ounces of hammer fall for 100% reliability using Remington Bucket Of Bullets. It even sets off my CCI Clean ammo with no problems. The DA pull ends up being 9 pounds 2 ounces, so, not much difference on paper but a major difference in the feel of the gun. I can pull through the trigger much better than my 7 pound DA pull on my 6 inch gun. The sights hardly move throughout the pull and my accuracy is much better. I'll do more tests and comparisons of the two guns but I'm very happy with the RevUp kit. Link to comment Share on other sites More sharing options...

Any way to check the weight on the second half of the movement? I’ve got a K/L hammer that I’m going to put in a new 617 that’s a test mule for things like this hammer.

Toolguy Posted January 12, 2023 Author Share Posted January 12, 2023 If you look on our RevUpAction.com website, you can see videos of a trigger pull gage I invented and built. Maybe you can get some ideas from it. Link to comment Share on other sites More sharing options...
gargoil66 Posted January 12, 2023 Share Posted January 12, 2023 (edited) Guys: My experience with the RUAH is much like Warren stated a number of months ago. Basically, it is a smooth trigger pull that begins harder than it ends. Smooth all the way through though. No hang ups but a guy has to be aware that it starts slow and speeds up as opposed to a consistent trigger pull found with a after market speed trigger / hammer that has been installed perfectly. As good as a perfectly tuned after market speed trigger and hammer? Sometimes I think so, other times am not sure. It does take some getting used to. Have also found that the faster the trigger pull, the more consistent and precise I am with the RUAH. It probably isn't a trigger for someone who likes to stage the pull. It can be done but takes some work. A pretty remarkable design. Two of them are working for me right now and I 'spect' the K frame will work in my 617.

Toolguy Posted January 12, 2023 Author Share Posted January 12, 2023 Thanks for your assessment, GG. It helps us to know how we're doing to get these field reports. Link to comment Share on other sites More sharing options...
AzShooter Posted January 14, 2023 Share Posted January 14, 2023 It's like Gargoil66 states. Hard to describe, it's a totally different trigger pull but I sure do like it. I still need to do some live fire testing with different ammo types but it likes my favorite, Remington Bucket Of Bullets just fine. I increased the DA pull to an average of 9.9 pounds and it still feels great. I'm doing a lot of dry firing to get use to it. Link to comment Share on other sites More sharing options...
Toolguy Posted January 14, 2023 Author Share Posted January 14, 2023 Thanks, guys! It is different, but you can't get different results by doing the same thing over and over. This one gives the trigger the leverage of a toggle linkage over the hammer. Similar to a reloading press linkage. The trigger smoothly gets easier to pull as the mechanical leverage increases over the hammer. Link to comment Share on other sites More sharing options...

Toolguy Posted January 15, 2023 Author Share Posted January 15, 2023 Yep - sounds like me with a lever action rifle. About every 3rd shot I get the trigger finger mashed between the bottom of the trigger and the lever coming up. That feels so good! NOT!!!!!!!!!!!!

gargoil66 Posted January 18, 2023 Share Posted January 18, 2023 And another RUAH installed with absolutely no problems at all. None. This one is in my 617 and the difference in trigger pulls is stunning. Went from a creeping and heavy pull to a smooth, positive and what feels like a much lighter pull. Will blast with it tomorrow to make sure it works with a variety of cheap .22 LR. $250.00, drop in, zero problems, go from a garbage trigger pull to a competitive trigger pull. All within twenty minutes and without one bit of fitting. Really remarkable. GG Link to comment Share on other sites More sharing options...
sousa Posted January 19, 2023 Share Posted January 19, 2023 Got mine and installed it on my 627 last night. Love it! I have the Pro Series, so the factory trigger wasn't totally horrendous. But this has changed it into a completely different animal. Can't wait to get it out to the range and do some tuning. Thank you again for making this product!

Toolguy Posted January 19, 2023 Author Share Posted January 19, 2023 gargoil66 and sousa - Thanks for the reviews. It looks like we're on the right track. I'm glad you all are enjoying these. There are other things in the works, can't say what just yet. Link to comment Share on other sites More sharing options...
mikey357 Posted June 29, 2023 Share Posted June 29, 2023 Haven't seen it mentioned anywhere, so I thought I would ask--Is the Firing Pin on the K- & L-Frame Kit of such a length as to be safe to Dryfire with in a Model 617? TIA... Link to comment Share on other sites More sharing options...
Toolguy Posted June 29, 2023 Author Share Posted June 29, 2023 It depends on your particular gun. Due to manufacturing variations, some are OK and some aren't. You can put an O ring over the firing pin so the hammer hits it, to dry fire. A 3/16 Id and 5/16 OD made of rubber or silicone works well. A small, pointy pair of tweezers is helpful to get it in and out. Don't forget to remove it before shooting. Link to comment Share on other sites More sharing options...

Toolguy Posted July 3, 2023 Author Share Posted July 3, 2023 17 hours ago, MedicGunGuy said: Do you have an ETA for the N Frame DAO hammers? Nothing specific. It's impossible to predict the future. There are only 2 of us, each running a business, with the gun parts business additional. I can tell you that it will be as soon as we can make it happen, just don't know when that will be. We are hoping to get the next production run done in a month or so. We may or may not make it, depending on the needs of our primary customers.
