Someone said Qualified steel sear is the best sear w/ unlimited calibers(?), anyone care to share their .02 cents?
thanks

Qualified sears and Flemming "H" Sears are the exact same thing. There is no difference other than the name. They are both worth the same money.

Yep, made on the same dies at the same time from the same stamped steel material and then heat treated. S&H sears are made of cast steel and are also high quality.

There are other more unusual designs out there (one piece trip lever and catch), but those 3 are what I consider the most desireable.

The Fleming and Qualified Sears, which are virtually identical, were stamped out of 'heat treated high carbon steel' at the same time out of the same stock. Fleming and Qualified Sears (carbon) are made of higher strength steel than the S & H Sears (tool). Also, it is not known if the S & H Sears were ever heat treated.

I think that Fleming may have made an earlier type sear before what is now called the Fleming "H" sear (serial number starts with the letter H followed by four numbers). The older Fleming sear has a different serial number approach (something other than starting with the letter H followed by four numbers).

I wonder if anyone has ever had these types of sears wear or break. I haven't heard of any personally. Anyone?

Not that I have all that much experience with sears to begin with, but the only broken sear I've ever even seen a picture of was a RDIAS from an AR. But it was the non-serialized part of it, so a replacement could be made.

They are a very low-stress part, and if hardened properly shouldn't ever wear out.

In my 12+ years of broadband internet connection to numerous firearm message boards, I have never heard of any HK sear, by any manufacturer breaking. Not even a "I know this guy, who knows this guy, who has a fat brother-in-law who stepped on a sear and broke it." If anyone ever breaks an HK sear, I'd love to see some pictures.

Post on Bowers board back in August wrt S&H sear breaking the leg under the trip lever.......sent sear to Urbach for the weld-up. Urbach tells poster he's done 4 or 5 before.......no follow-up on the repair from original poster. With Urbach doing the work, he could already have it back and not posted a follow-up, or.........he might not get his sear back in the foreseeable future.

I still favor the Fleming/Qualified sears.......just my preference.

I also recall a subguns.com poster who showed pictures of a Ciener sear that had the trip arm broken off. This is one of the single trip designs and that long arm sticking up out of the pack to impact the carrier tends to concentrate force.

Don't know how it happened, and don't know how it got fixed, but he did have pictures, and a convincing story.

Anything metal will wear, and if too much pressure exists, will break.

And that is why the Fleming sear is more desireable over the S&H sear but I have personally never heard of any of the two ever breaking or wearing out.

As I'm not a "smith" I wasn't sure how much force/wear the H types sears could expcet to have...guess I could contact S&H and ask.

Some sear packs are easier to trip the sear lever than others. My sear pack takes a lot of force like a stock HK sear pack while a friend of mines sear pack with a S&H sear will trip very easily. I would imagine the easier the sear lever trips the less wear or chance of breakage will be but I guess it just depends where the sear location is in the pack & what spring was used.
