Mark Camoc­cio’s re­view of the Walther LGU Mas­ter Pro break-bar­rel springer - Part Two

Last month, we be­gan look­ing at the top end, fully tuned Walther Mas­ter Pro. This month, we take a look in­side. Walther named the pro­cesses be­hind their ap­plied tech­nol­ogy, and they are summed up as fol­lows:


Su­per Silent Tech­nol­ogy is how Walther terms the mea­sures taken to re­duce noise in the ri­fle’s ac­tion. ‘ Zero-play fit’ refers to the added ny­lon bushes and small pads around the in­ter­nal bear­ing sur­faces; the bar­rel lock, and cock­ing rod. Run these smooth, and the whole cock­ing op­er­a­tion is slick and con­trolled.


The Vi­bra­tion Re­duc­tion Sys­tem is how Walther terms their process for en­sur­ing an ul­tra-smooth fir­ing cy­cle, achieved by in­cor­po­rat­ing pis­ton rings made from a low-fric­tion syn­thetic ma­te­rial. This re­sults in zero play around the pis­ton. All as­pects of de­sign were mon­i­tored in de­vel­op­ment, and the re­sult is an ‘op­ti­mised’ pis­ton, that breaks on an air cush­ion at the end of its travel. It’s also al­lowed to ro­tate fully, with ‘anti-torque’ built in. Walther also drills trans­fer holes for each en­ergy level, at op­ti­mum lo­ca­tions, and these all help to re­duce re­coil. The main­spring is man­u­fac­tured from tem­pered valve-spring wire, whilst a full-length, close-fit­ting spring guide is also fit­ted as stan­dard, all but elim­i­nat­ing res­o­nance.


As you may have re­alised, this is a com­pre­hen­sive, no half mea­sures ex­er­cise, and shoot­ing the Mas­ter Pro re­veals a thor­ough­bred that re­ally does de­liver on all counts. As with all the LGV mod­els, that su­per-solid bar­rel lock sys­tem lies at its heart, and its op­er­a­tion soon be­comes sec­ond na­ture. To cock the ac­tion, squeeze the bar­rel and catch to­gether, and the breech will then open eas­ily. The bar­rel is semi-car­bine length at 15.5inches, so no ma­jor lever­age ad­van­tage, yet grip the bar­rel weight and adopt a pos­i­tive down­wards stroke, and the ef­fort is rea­son­able.

The cock­ing stroke it­self is in­cred­i­bly smooth and de­void of any spring graunch, as you would ex­pect. With the Mas­ter Pro bro­ken, a pel­let can then be pushed home flush in the crisply ma­chined breech face. Look care­fully at the open breech block, and the small cut- out in­cor­po­rated into the pro­file is fur­ther ev­i­dence that a per­fect se­cure lock-up will be achieved. Close the breech and the lock au­to­mat­i­cally comes into play. This model comes with an au­to­matic safety catch, and the shot­gun­style catch just needs to be thumbed off at the rear of the cylin­der.

A gun of this class ob­vi­ously de­serves a de­cent trig­ger, and this model gets Walther’s XM unit, a fully-ad­justable, two-stage de­sign. On test, I did find the

first-stage travel too long, although my ad­just­ment skills are not the best! How­ever, that sat­is­fy­ingly flat trig­ger blade and sen­si­tive mech­a­nism over­all, only help to pro­mote top- grade ac­cu­racy. As you fire the LGV Mas­ter Pro, you sud­denly ap­pre­ci­ate the level of prepa­ra­tion that goes into its pro­duc­tion, as all those so­phis­ti­cated com­po­nents come to­gether as one. Of course, there is still re­coil, but the fir­ing cy­cle is de­void of any spring twang or res­o­nance – rather just a slick snap, and the shot is gone.


Next stop was the chrono­graph, to see just how con­sis­tent the power plant could be. Of course, we can get too hung up on min­i­mum vari­a­tion ve­loc­ity fig­ures, but it is al­ways im­mensely sat­is­fy­ing to see those fig­ures come in. With the LGV Mas­ter Pro, I ini­tially recorded very cred­itable 10-shot strings of 10fps shot to shot, with both Air Arms Di­abolo Field ammo, and Ac­cu­pells, straight from the tin. Ac­cu­racy was also im­pres­sive, as you would ex­pect, but with a va­ri­ety of am­mu­ni­tion, which is al­ways pleas­ing; 3/8” cen­tre-to- cen­tre groups were posted with RWS Su­per­dome in .177, shot over 30 yards from an FT over-arm po­si­tion. Yet switch­ing to Air Arms Di­abolo Ex­press re­duced the groups still fur­ther, down to just a quar­ter inch cen­tre-to- cen­tre, again over 30 yards. Su­perb re­sults and proof, if it were needed, why the LGV mod­els have been so well re­ceived since their in­tro­duc­tion.


I liked the stan­dard LGV when it first came out, but the stock was bland, and it was rather ex­pen­sive, too. This lat­est Walther LGV Mas­ter Pro now of­fers a great han­dling, su­perbly made clas­sic sporter that looks bril­liant, and shoots with real aplomb. The down­side has to be the weight, and that fairly short bar­rel, mean­ing cock­ing ef­fort is greater than some ri­vals. Yet for any rea­son­ably fit adult, the sheer pedi­gree of this Walther must edge into any short list. The ac­tion feels gen­uinely fully tuned, straight from the box, al­ways the man­u­fac­turer’s in­ten­tion, and with an un­beat­able level of per­for­mance on of­fer, this model can han­dle any­thing asked of it, be that field tar­get, HFT, or short hunt­ing trips.

I’m not quite sure how they make it in Ger­many for the money, but hav­ing seen that pro­duc­tion line, I’m def­i­nitely a fan of the Walther Mas­ter Pro – surely one of the very best value, top- class spring guns cur­rently avail­able.
