The Tikka saftey (Sako) is an adopted unit across the two brands
The Sako whilst more complex and allows the user to manipulate the bolt whilst “on safe” does not block the firing pin
One rarely hears if failure of either unit through mechanical fault or breakage
Any issues are usually caused by end users putting in significantly weaker sear springs and either failing to follow manufacture guidelines on safe operating tolerances or being on the Darwin spectrum (or both)
Lower spring rate causes lack of positive sear engagement / reset
As Blaser have been mentioned - there have been some well documented failure (ND) reported around the saftey of R93 and R8
They are two doffernt systems but both operated by sliding the decock device at the rear of the bolt body on the tang
Many failures occur when end users do not follow the manual and allow fingers within the trigger bow whilst sliding the de cock
The pressure required will in some instances cause involuntary grip and pressure on the trigger - the end result being a ND
Dirt ingress in the case if the R93 is another well known issue with sear engagement
Back on task
The AsH Tikka saftey was (is) a solution for those who wanted a true three position saftey device for T3
Though looking at the web page, I’m not sure if it’s still in production
It worked but required some “fitting” (just like any other three position saftey)
They are rarely if ever a drop in fit (ask me how I know),,,,after spending three days of hand filing - fitting a device to a dangerous game rifle
Basic principles of rifke handling should be applied when removing chambered rounds from any rifle
Even with blocked firing pin on 3 pos saftey this should be followed
Tikkas have a pretty good saftey record
End users ,,, that’s another story
